I did not catch the beginning of this thread... what year is the car in question? If it's before 1989, the Check Engine light only turns on when there is a "massive" failure in the mixture - either a result of a failed O2 sensor, disconnected air mass meter, etc. This condition will result in poor performance... *really* poor performance. On '89 and later cars, using LH 2.4, the Check Engine light will come on during simple mixture problems, or other faults. These faults will be stored in the ECU and can be retrieved. In these cars, a check engine light can result in really poor performance or simple, occassional drivability problems. Most likely, the problem will be the air mass meter or the O2 sensor. A little more info and I might be able to help. -Justin
