Have a '98 Sunfire Convertible with about 140,000 miles. This car has run great for the last 100,000 miles, with the only problems being door electric window actuator and switches, and similar problems. For the last year or so, the car has occasionally hesitated to accelerated, or tried to die at idle, especially after being started warm. Used to be able to cure this, it seemed, by putting in neutral and revving up the engine a bit. Lately, this has suddenly become a daily occurrence, and it now occasionally shows the check engine light. Every thing else seem normal. Took it to a shop and it showed only a "rich" code. Okay, experts. Anyone got any ideas?

Took it to a new shop in town, with high recommendations. The young mechanic had won a national troubleshooting competition. He had the car back out in the parking lot in less than 10 minutes, having replaced a cracked vacuum hose. Turns out his dad had won the Plymouth national troubleshooting competition in 1974 also. Guess trouble shooting runs in the family. |
