Well a few weeks back I got a CEL for rich fuel mixture that went away and came back twice. Now it is back to stay and the car is noticeably driving very badly.
Today I was boosting into the red (2001 9-3 base, no mods), but it felt like I was barely boosting at all. I floored her in 3rd out of frustration to see what would happen and BANG, followed by engine failure! It took a bit to realize what had happened but the air delivery pipe just behind the plastic engine cover had popped off and cracked the plastic cover in the process. Ok so no biggie, I put it back on and clamped it down real tight. I was actually happy about it, thinking that it must have been somewhat loose all along, and thus i was losing some of that pressure and getting bad performance and was running rich from the lack of air. Well that was wrong...
Now it is boosting normally but I dont feel the power at the peak of the powerband. The engine revs normally, the turbo gauge goes up to its normal postion in the yellow, but I am not accelerating very well at all, and acceleration kind of yo-yo's up and down, instead of a nice smooth power curve.. If I then floor it and try to get more power out of it, acceleration will ramp up then back off sharply followed by some strange rapid clacking noise !
If i drive like a grandma everything seems to be ok except when on my way home from this testing, at a stop light it started idling very very hard as if it was going to die, then resumed normalcy, then went rough again, then normal, then fine until I got home.
Any ideas? If not hopefully i can have it looked at by a professional tomorrow. I really need the car right now though. At the moment I am keeping her grounded .
