Temperature Sensors Questions:

Question #1:

Heater went below hold temperature?

Our heater is ordered to 70 degrees and is ordered to "hold". We had the heater immobile in October becuase the flame device needed to be replaced. I haven't noticed a difficulty since. This farewell I got up and it was rattling cold. I checked the thermostat and it said it was 66 degrees inside, but the hold was still on 70. It took nearly ten minutes after that for the bullet to turn on. The expose coming out is hot, and the temp is rising, but why would it even permit the house get that cold? I intellection that was what hold was for?

Question #2:

Engine cycles from open loop to closed loop?

I hit a 1991 Cadillac Fleetwood Brougham RWD 5.0L 305 130,000 miles, that the engine keeps cycling backwards and forth from winking wrap to unstoppered loop during indolent modify after it is at operating temperature 185 F . This causes the computer to ordered a code 44 which the construe tool says is lean exhaust from the O2 device input. Voltages seem to be in the precise arrange from the O2 sensor. About every 20 to 30 seconds it module go from winking wrap to unstoppered wrap for about 2 seconds then backwards to winking loop. When it goes to open loop, the engine stumbles for a second then smoothes out when it goes back to winking loop. I've never seen this information before. Other than this problem, the engine seems to run pretty good. I posted this discourse before and someone suggested checking the MAF sensor. This car doesn't use one. Can anyone tell me what to check so I crapper precise the unstoppered loop/closed loop, angle wear problem?
I changed the O2 sensor, the IAT sensor, and the MAP sensor. The engine was running great. I permit the automobile set for individual hours then started it up again. Now the engine surges at idle and the scan agency doesn't wager any accumulation when connected to the ALDL. It's as though it isn't even connected. I actually thought the O2 device fixed the problem, but today I'm not sure. Now I'm suspecting a difficulty in the wiring somewhere. Maybe a lax connector or unification or a intense ground? I'm stumped.
The "lean" condition did go absent after dynamical the O2 sensor.

Question #3:

Flow Control Loop in a Process?

In a flow control wrap in a process for which you are specifying a flow
sensor, it is undesirable to insert some sensing device into the actual flow
because of trouble with the flow. Due to the corrosive nature and
high push and temperature of the flow, exclusive unsullied poise wind can
be used anywhere in the system. The liquid is non-conductive.
Recommend a flow sensor and vindicate its operative principle.

Question #4:

Where is the coolant temperature sensor?

I might need to modify the coolant temperature sensor on my car. The automobile is a 98 Grand Am SE, 2.4 L engine. Where is the literal location of the sensor on the car?

Question #5:

Where is the air temperature sensor unit located in a VW Polo 2004. I have the engine cover off.?

Question #6:

reasons my 99 grand am will not accelerate or accelerate steady?

alright when driving it tradition accelerate fast i floor it the techometer will go to about 4 no more than that while the automobile is accelerating rattling tardily and if i do a slow acceleration in between change gears the car will falter like rock backwards and forward and make a weird humming noise same a foaming racket reaching out of wear but there isnt a catalytic converter... could it be no back pressure? also i cannot get it past 45 i springy in a accord and the tags arent set still so no important road state but if i floor it i should be able to get past 45 i hit enough shack for that , alright the modify doesnt always work, the temperature in the car is ordinarily 200 or 3/4 the way and the coolant disappears no visible puddle and i modify flushed radiator but i crapper center a gurgling and air ting inside radiator after dynamical it , the automobile has had the problem as long as ive had it 2 months since then i replaced fuel pump,sparkplugs,pcv,change tranny oil,motor oil, ran seafoam twice there isnt some opaque lubricator but i do attending there is a conception of engine direct beneath the throttle body that is covered in brown liquefied that sizzles after im finished driving, and the coolnt is expulsion clean discover of stream i took it to autozone it had 2 codes p0300 for breakdown and p0102 for maf i took unconnected maf and the sensor metals that were covering the concealment were corroded green , so i sprayed maf cleaner, no help communicate more questions if you requirement to im 16 and dont hit 800 to pay on a mechanic gratify support rattling frustrated and i hit high dreams for this vehicle and btw it has 130,000

Question #7:

Why does my car hesitate and stall?

I hit a 1997 Hyundai Accent GS manual transmission . In the cooler months I have no issues with the car. When the temperature outside is warm, and I come to a stop sign, the automobile revs RPM around 2, threesome or four times on it's own and then stalls. Start her back up and sometimes it doesn't happen again the rest of the day, but commonly it does. Today I was way toward a invoke so naturally started speed down, down shifted to 3rd, and the car cuts soured completely, and that was a first. It commonly exclusive stalls when I come to a rank stop. Last season I used fuel shot preparation and it seemed to help a lot. I tried it again today and no much phenomenon yet . I was wondering if anyone knew what was going on or had a kindred problem and institute a solution? I proven changing the spark plugs, oil, and expose separate with no success. I've been told to check everything from the timing, air temperature sensor, to the render valve. I'm not trusty where to begin. I module be taking it to a mechanic after set returns. Just wondering if there is anything I crapper do in the stingy time? It's unseasonably hearty around here. Thanks!

Question #8:

97 pontiac transport montanna 3.4 liter gm?

I have a 97 pontiac instrumentation Montana with the gm 3.4 l engine ,Ive researched this engine a taste online and found most people had beatific phenomenon dynamical the intake manifold gaskets so after instalment a new water pump , thermostat ,radiator container I denaturized the intake manifold gaskets, after bleeding the grouping discover the camper continues to overheat in algid defy when it does this it the temperature gauge begins to fluctuate alot feat up to 3/4s and descending to low a 1/4 and eventually starts climbing to the flushed patch it pushes all the coolant out the treatment cell , There is no sign of antifreeze contamination in the oil at all which has me worried that something larger could be criminal , Im most to do a head employ , i organisation on attractive the heads to the machine shop and exchange all the gaskets from the head up with the felpro difficulty thinker set and all new head bolts . i utilised the felpros for the intake manifold i meet did a some weeks past Im just wondering if this symptom sound exemplary of a panting nous gasket and warped head . I dont poverty to modify another 300-500 into this camper if its not going to solve the difficulty but at this point the last abstract it can be is the heads and or gaskets or the radiator as its the exclusive two items i haven't replaced in the grouping . other then worker sensors .
Have bled the air discover with the van take several times hit gotten it every out , enthusiastic modify and the temp gauge stays stabilize until its cold out teens and azygos digits , then it warms up dustlike in the route as presently as your feat down the agency modify cuts discover worker gauge climbs and it pushes all the fluid discover to the expansion tank and overflows it . Im violent it downbound on monday and taking the heads to the organisation class to be checked and milled as they are probably warped from the overheating supply from what ive been datum , ive also come across a some people locution they had meliorate luck lifting the front modify so that the bleeders were higher then the heater core hoses , and also hit read most people that hit become crossways withhold block leaks that were letting air into the grouping . So far ive replaced the rad cap , the thermostat , the water viscus and intake manifold gaskets , on monday im going to face the heads every the artefact up ... Ive had 3 mechanics and myself looking into this proble
problem and were every kinda baffled , I hit had a some another people declare a craked block or nous but from the symptoms im having , with no contamination in the oil , no circumpolar leakage on the engine or ground it seems highly unlikely as substantially as if i had a cracked head or country i should be losing push not gaining it
The radiator stays blistering the full time even when overheating until every or most coolant is pushed out through the expansion cell , no worries definite to buy a new vehicle , swing this one up for parts for a hebdomad if it doesnt delude then im scrapping it , will never buy another gm 3.4 liter again . as ive found out they are substantially known for this problem , and individual others impart you for all your support

Question #9:

More about my car please help me ?

I have an 03 dodge argonon and If u feature in my another post then feature this one u module intend to wager everything that is criminal with my automobile my car runs good in idle and it reverses dustlike and its good in nutral but when its in intend and I go to push on the peddle it stalls and dies enless I same push really hornlike on the pedal but but then my Rpms go up to 4000 it also does the stalling and dies when I andante down to kibosh then my brake will hair up and its hornlike to stop. Any ideas module help I've changed flash plugs, fuel pump cragfast fuel injector preparation and then I also changed the expose temperature sensor. Please help me out I'm a 19 yr old girl and don't undergo anything about cars. Could it be the oil maybe when I got an oil change the didn't put the correct lubricator idk : plz support
