I have a 2002 Volkswagen New Beetle 2.0L with 142,000 miles. Just last week I had the timing belt and the catalytic converter replaced. For about a month now my car has had an issue with its idle. When I come to a stop sign, the idle drops down under 800 rpm and the car shudders. If I put the car in park and gently push the gas pedal, the shuddering stops, and there had been no problems while I was driving.
Today, though, I had been driving my car for no more than five minutes when it shuddered and the check engine light started blinking. I immediately pulled over and shut the car off. After two or three minutes, I turned the car back on. The light didn't come back on, and I drove the rest of the way home (about a mile) without any new issues.
I can't go to Autozone to get the code checked, because the light is not on. What could be causing my problem?
