idle issues and stallling out after cleaning the iac and doing a coolant bleed
i have a 92 honda prelude si with a h23. I have cleaned the iac and i have also bled the coolant and now the idle is bad and the car is wanting to stall and jump? Any idea on how to fix this issue

Re: idle issues and stallling out after cleaning the iac and doing a coolant bleed
if you sprayed anything inside the iacv you may have damaged the seals inside that do not like chemicals
you only want to clean off the outer metal mesh

are you sure you plugged everything back together correctly?
did you do anything else than that?

usually these things fix bad idle or/and hesitations:
- new spark plugs & wires
- new distributor cap & rotor
- new air/fuel filters
- clean injectors/iacv/egr/fitv
- bleed the coolant
- new pcv
- adjust valves and ignition
- adjust idle from tb's screw and throttle cable
- check does sensors work properly: map, iat and tps (and try calibrating tps)
- then check wires, connectors and hoses
- check ICM and ignition switch (there was 5th gen repair call for this also)
check o2 sensors and vacuum/exhaust leaks (check all the seals - IM/header/TB gaskets, injector seals, maybe even buy valve cover gasket set...)
check timing. after that: double check timing
clogged cat might you give some trouble as well (usually when driving) - check cats condition
if none of these seem to work - do compression and leak tests
and if you have chipped ecu and youre running it just with basemap, it might not work as well than properly tuned one
those are basic maintenance as well.
