Ok, heres the problem.
I drive a '99 Escort
A little while ago, the 'service engine soon' light came on. I took it to a mechanic to run the computer on it. It returned that the idle air control valve was no good anymore. No big deal, right. I ordered a new one. Put it on...and things got worse. WHen the car would idle, it would idle very high and it seemed as if the valve was 'kicking in' at the wrong time. After I would relaese the break, the car would speed up to about 15 pr
20 mph w/0 me even hitting the gas peddle. So I promptly took the new valve out and replaced it with the old one.
Now here is my wuestion. Did I have to do anything special...such as 're-set' the car cmputer after i insitalled the new part. Im not sure when it comes to computer components in my car. Any help would be greatly appreciated.
