hey guys i posteed a while back about my car having a really high idle ive changed every sensor but the map an nothing has changed. i have found that the computer gets really hot like hot enough to burn you. The check engine light comes on but it doesnt save any codes and when it does this high idle thing the scanner loses its connection to the computer? ive checked every wire from the computer they all have the right voltages and what not, the only problem is i can never get it to idle weird when im checking the wires. Is the computer just shot or could something be cuasing it to mess up? it only idles high after ive driven about 30 miles or for aroound forty minutes.

 

you should post this in the proper section. if the mil light come on and it doesn't store any codes I would say its bad. The ecm has transistors that dissipate heat through the casing. you may also check your bcc for updates.
