If your Malfunction Indicator Light is on it may be something simple causing it. A few tips to avoid this problem:
- Always use premium, high quality (brand names like Shell, Amoco, BP, Mobil,
Chevron) fuel.
- Do not start your car and shut it right off (such as when you up move it out into the
driveway or somewhere else where it doesn't run for at least 5 minutes or so), as this can
easily foul a spark plug. (1.8t's have a significant problem with this. No flames please, it's
fact!)
- Don't. repeat, don't give your car ANY gas while starting it. You have a modern, fuel
injected system that gives itself enough gas at start up. Giving it gas while starting will
hurt the startup procedure.
- Tighten your gas cap very well after each fill up. This is the problem in 70% of the OBD II faults!
