Hi,
Was wondering if any of you have seen this?
Occasionally, I will be dring my SC around, and the car will start running rough. A few miles, sometimes more after the CHECK ENGINE LIGHT WILL come on and start acting REALLY funny, misfires, stutters, and eventually will stall. Trying to restart the engine results in cranking but no start. Engine just keeps turning over.
If I take my EEC Tuner out the car is fine back with the stock computer and starts right up and drives. Obviously I can't drive this way with the 4.2 I'm using so I have to gently limp it home until I reprogram my Tuner and then the car is good to go again sometimes for 50 miles, sometimes for 5000 miles.
It's like the Tuner is losing its memory or the stock computer is trying to overtake the Tuner. Do you think it may be a problem with the factory computer? With the tuner chip itself. I even replaced the 30 pin AMP connector pins with brand new amp pins and still no luck. It's repeatable again and again, but since it happens at different intervals I'm not sure where the problem lies. And it doesn't happen under specific condittions. Sometimes it happens under WOT, sometimes partial throttle, and Sometimes it happens under cruise.
Just curious if anyone had any suggestions.
Thanks for any input.
