I'm at my wits' end with trying to figure out the throttle problem so I'm wondering if the DME itself is messing up. Is there a way for me to test it or do I have to give up and go to a dealer?

I think I've done everything else I can to try and remedy the problem. The E-Gas throttle will not go over 2K rpm and gives me the code P1502. If I clear the code, the car runs beautifully until you turn off the engine and restart it. That's the case whether the engine is cold, warm or hot. I have checked for vacuum leaks and replaced the MAF, O2 sensors, fuel pump relay and throttle body. I don't know what else could cause this problem and go away when the code is cleared unless it's a problem with the DME.

TIA!
