Hey everyone, I have a 97 Ex ... just swapped on a new block. No leaks or anything, but when it starts the idle pulses. revs to about 2000rpm then goes down to 800rpm and back up constantly... then it will die out. I can't seem to figure out the problem. I was thinking it was a sensor problem but im not positive. Anyone know how to do anything with the ECU to bypass sensor problems? OR have anything that might solve this? I know my friend said he had a problem like this and it was an iavc (sp?) valve or something... any input would help me. Thanks in advance.

 

did u double check all ur connections..?? IAC, FITV, ect.....

 

Typical IACv problem.
(idle air control valve)
