Oh shi*t, this sucks. I took the EGR valve off my car to see if it was working properly. It was really clogged so I cleaned it, cut a new gasket and reinstalled it. When I started the car, it backfired shortly after starting, blorting a huge black stain all over my driveway, and then idled rougher than sandpaper, then stalled. From here, it would not start anymore, just turn over and occasionally a plug or 2 would fire.
So far, I THINK that not all pistons are firing as normal. It sounds like sometimes some are missing. Lots of exhaust comes out the back end and it smells VERY rich of gasoline, which also leads me to believe not all pistons are firing.
I pulled the plugs and cleaned them (werent too dirty, just a bit fouled from rich mixture) and reinstalled them. It started on the first try, but went back to the nasty rough idle right away. I'd have to practically floor it just to keep it running, and the more pedal I gave it, the more it would misfire. So I let off, and it died again.
Next, I pulled the EGR valve off again, and tried starting it. It runs really rough, and also at about 2500 RPM (1900 with idle adjust ALL the way closed). Exhaust was coming out of the EGR tube from the exh. manifold like it was supposed to, and TONS of air was being sucked into the other hole into the intake. I could cover up the intake hole and the idle would drop down, and it all sounded like it was running pretty smooth, but when I open the throttle, it gets sick again, puffing out un/partially burned gass and trying to stall.
Someone PLEASE tell me what I did wrong!!! Could a bug or something have fallen into the intake hole while I was answering the phone? It was running BEAUUUUUTIFULLY until I took the stupid EGR valve off and cleaned it.
