Re: Check Engine
From what I've seen, it could be a multitude of issues. Alot of people seem to have different fixes to resolve the issue. These were most of the common ones that seemed to fix that issue. The most common seemed to be fuel filter and o2 sensor sending a false cel because it is going out. But here are some of the other ones I have seen.
Fuel supply system, Primary O2 sensor, MAP sensor, contaminated fuel, valve clearance, exhaust system.
Hope that helps.

Re: Check Engine
Did a little research and alot of people said cleaning or replacing IAV fixed their issue too. I'd start with the cheaper items and go from there.
