Was that on a 7mge, mine is a gte. Well I changed the spark plugs and checked the timing and it ran a little better but it still sounds like its misfiring. I found one air leak on the back side of the intake. It is a steel hose that bolts to the intake. Its a very small air leak so I don't think it would be causing it to idle down to 400 rpm's and killing it. I really wish I could figure this out.
