my friend drove my 88 crx dx into a ditch he fried the ecu but everthing else seems to be fine we threw another pm5 ecu in but its an automatic car. It runs fine but idles around 2000 and surges once in a while. I unplugged the IAVC and it idles fine I took it out and tested it and seems to be working properly something must be giving it a false signal I'm thinking some sort of temperature sensor. Any sugestions????

 

Anyone??
