Any idea on what could cause this??? When idleing, or just driving around the car is missing and acting wierd. When it's just idleing it has a miss (hiccup in the exhaust) There's no loss in power at all that I can feel, I took out the MAF meter and cleaned it, and checked all the vacuum lines, and it still does it.

 

Try cleaning out your IAC (idle air control valve) with some carb cleaner and wd40

 

Try changing your plugs!

 

Is it throwing a code?

 

no codes at all

 

I feel your pain since I am wrestling wiht a similar problem. In fact, mine is soo bad the car is not drivable.

If I were you I would start with Ed Clark since he tuned it and go from there. I am sure he will tell you to do a few things and then bring the car in if that does not solve the problem.

 

oh man that sucks, mine isn't that bad, it still runs good if I put some ear pugs in, and can't hear the horrible missing. I've already cleaned the MAF, IAC, and today I'm gonna change the plugs. If that doesn't fix it I'm going back to Steen, and putting it on life support......
