When I returned I looked low and noticed the converter was still glowing. I did some investigate and my symptoms matching up to a filthy or intense EGR valve. After researching the backround of my car I became aware the previous owner had it cleaned before. So I opted for the replacement 180 . I took the older digit off, cleaned out the port, reapplied the gasket and place the newborn one on. When I started the car it still ran rough, but idled better. I proceeded to intend up the road, when the car started bucking, made a racket same pressure emotional but loud then died. After getting it backwards into the driveway, I proven to move it again and it wanted to start but wouldn't. I then detected oil leaking out pretty good when we proven to start it from every around the lubricator pan. I'm lost! Car ever ran beatific up until last week. I don't know wtf happened! If anyone crapper help me PLEASE! I just lost my job and my house was part of my salary! I can't afford to throw anymore well needed to a forfeited cause!

Question #9:
Recently my engine light came on on my 02 Grand Prix 3.1. Got it patterned and the code came up for the EGR valve.I changed it. The automobile ran dustlike for individual life and then the engine light came back on. This time it came up as the Mass Air Flow Sensor, I denaturized that also and the car ran ok for about a day. I talked to individual execution and they all said to essay dynamical the fuel filter next. I did this and now the automobile is worsened now and will just get up to 20 mph. I was told to essay dynamical my spark plugs and it did not support at all. Talked to individual people and they have every said it could be anything from filthy injectors to a clogged catalytic convertor. Help please!!! Thanks.
The car started running rattling sluggish problems going up hills, taking off, etc before the reddened came on. Changed the egr and it immobile it for a few days, but light came back on as it progressively got worse. Changed masf and did not help any. Changed fuel filter and it is worsened that when the initial problem started.
render filter exclusive goes on 1 way so it is not backwards.
Question #10:
Engine makes blasting noise noise after 20 minutes of driving when going from 0 to 40mph, and its hornlike to accelerate, i heard it could be the knock sensor or EGR valve, some help?
Thanks
Edit: solon details- After the automobile reaches 40 or 50 mph, it accelerates a lot meliorate and the engine humming sounds same I'm working the engine a lot harder than I am , the wave and the engine humming noise only occurs while accelerating not at idle, engine sounds dead connatural at idle. Car makes 2 assorted noises- the wave noise when I accelerate is assorted than the humming racket but I undergo they're related b/c everything is ornamentation until after 20 transactions of driving...hence maybe nonfunctional Knock Sensor??
