Any advice, suggestions, very much appreciated....
Last week driving to work was stuck in construction on the highway - stop and go for about 7 miles, up to 5mph at the fastest. After being stuck for about 10 minutes, noticed the RPMs were climbing when I came to a complete stop. Even with the car in neutral, ebrake up, (No, the floor mats weren't hitting the gas) I was idling at about 2500. After another 5 minutes I was at 3000, and within 10 minutes I was at 4000. Finally pulled over and turned the car off for 10 minutes. Turned it back on and I went right up to 5000.
So...I unplugged the idle control valve and drove the rest of the way in. Idle was rough, obviously, but normal.
Yesterday I replaced the valve completely, plugged everything back in, and seemed fine - until about 10 minutes of city driving sent my idling back up to 2500 at a stop sign, and within another 5 minutes, I was at 5000!!!!
Anyone have thoughts? Throttle wire? Computer? I've noticed a few similar threads but nothing that seemed completely resolved?
