I reset the ECU and drove it work today(15 miles each way). The light did not come back on today and the car seemed to be driving fine. Besides putting the car on a lift, is there any way to check if i damaged something on the exhaust system since the exhaust runs right next to the oil pan??? Also, Is JB WELDING really that bad of an idea, because I have read some postings by people on some other sites that have said it has worked fine as long as you do it right.
