See the thread for engine surge. The saga continues. I followed the idle relearn procedure several times but the engine continues to surge from 1000 to 2200rpm about 7 times per minute. There is no check engine light. I am convinced that this electrical plug is causing the problem. I removed the battery, air filter box, intake manifold, jacked up the car and used a flashlight and mirror and am in able to find where it connects to. I took a picture of it. I am unable to figure out how to post the pictures. Car and personal computers are giving me a fit.
