Engine Performance problem
2000 Acura Integra 4 cyl Two Wheel Drive Manual 73000 miles
There's no CEL and only happens when it's fully warmed up. First occurance was last week.
The problem occurs at 1k to 2k rpm and a slight miss at 2.5k occasionally. After that and when the car is still cold, the car drives well. If when the car bogs and I try to slam the throttle to get out of it, the car stalls completely.
First gear isn't much of an issue because it goes through that rpm range quickly at little throttle pressure but the other gears have this problem. I also found out that it doesn't occur if the throttle is slightly pressed but misses when I push in a little more.
I have not changed anything on the car; it ran well prior to the problem.
I have a narrow band a/f gauge that shows a constant sweep which is why I don't think it's the o2 sensor (but not throwing it out of the question).
What can cause this problem?
have the same problem?
