motor will not idle up when a/c kicks in
 

ok i have a 98 ex and just swapped out the bottom end
now my a/c will not idle back up when the compressor kicks in
i also am having a sporadic idle (sometimes its at 900 rpms and ill hit the throttle and then it will go back down)
again i changed nothing but the bottom end
need some possible things to check out to start problem solving
thanks all

Re:motor will not idle up when a/c kicks in
 

vacuume leaks are the main causes of idle problems. also make sure your o2 sensors are hooked up properly, a cable on my cars' o2 came off and it would idle rough. there's also a sensor for the idle. but chances are it's a vacuume leak.

youll never guess this!
found it on honda tech
the plugs for the IACV and the evap solenoid are the same but diff wires
MINE WERE REVERSED!!!
swapped the 2 plugs and all is fine
over 5 week replacing everything
wow
make this a sticky!!!
IACV plug should be yellow/black wire and a blue/black wire
not GREEN
