I have a 2002 civic ex SOHC with 84000 ,miles. my car check engine light just started blinking and i have full range of rpm and then about 20 seconds later the engine light stops blinking and remains on and my rpms top out about 2500 rpms and my a/c is not turning on, and my cluster shuts down. I just did a service on it and also replaced the belts and put gas treatment like i always do every other oil change.I tryed scanning the car for a trouble code and came up with link error in the middle of scanning. I also used my mechanics scanner and his finds no trouble codes but also does not reciecve half of the information.Any ideas.
