What would cause my car's speed to increase after I let off the gas? The car runs fine other then that, I cleaned the throttle plate, and poured techron in the tank, checked vacuum hoses. The car has no trouble codes. The problem seems to be increasing. It doesnt happen all the time, but more often now I noticed the speed slowly increases instead of decreasing after I let off the gas. I'm usually going between 30-40 mph when I notice this, I occasionaly have a high then normal idle at start up also. Any idea's?
