1993 Convertable,
My idle just started hanging on the high side, around 1500.
It acted like it was sticking so I lubed all the linkeges in and around the trottle body but it still is at around 1100-1200.
Don't think it helped much. Could this be a sensor problem? Had the water temp sensor replaced last winter and just replaced the plugs. Any Ideas?

check your tps. May need to be cleaned. Try some redline injector cleaner and make sure all you coil packs are working properly. Check coil pack and injector connector connections for corrosion.

It could be your AAC valve or TPS or both. Read the instructions above. I have th same problem. Cleaning the AAC valve didnt help so i ordered a new one. Waiting for shipping.
Aslo clean your Throttle Body as well.

 

Thanks for the replies. Could you please tell me the price
of the AAC valve and if it worked. Thanks, Dave
