Noticed it the first time I drove it from dealers lots, used of course, once the engine warms up, between 2 and 3 thousand RPMs, it seems as if power is lost. Pushing in the clutch or adjusting the throttle placement corrects it. Motor never quits, it just spits and sputters then goes on about its business. I've added a grounding kit, changed the fuel filter, complete tune up, had the TPS rewired, added a KNG air filter and nothing has worked.

The computer throws NO codes to help with the matter. The OBD computer was replaced 3 years ago, that didn't help. I bought the car with 90,000 miles on it and again it has done it sense day one. It isn't all the time, it is intermittently, I've had it to 3 different shops and no one can figure it out.

Any help appreciated.
