When I go WOT my car starts to sputter or choke. I noticed the problem last night and my CEL light came on. It accelerates fine and I can take it up to high rpms with no problem, but once I go WOT my car starts sputtering. I don't know what would cause this but I did have an exhaust leak but I'm pretty sure I fixed it. I also just changed my spark plugs a few days ago. Anybody have any ideas as to what's going on with my car?

 

Did you use the same plugs? What are the gap on the new plugs you put in?

 

Get the code read.
