i got a h22 in a 92 hatch. i can drive it a bit and then when i stop the idle drops to almost 0 than jumps up to 1k. it vibrates like it wants to die than surges. what's going on?

bump I have the same problem...coming to a stop and putting in the clutch the idle will drop to zero then come back up to 800rpm.Bump for info

Would it be the idle control valve?

my sol does this as well, but only after driving at highway speeds and coming to a stop(like exiting the highway)...i alaways assume its just the fuel trim re-adjusting...my car has never actually stalled out from this

what sucks is i go to a red light and my cd starts skippin. plus at night if im at a red light my headlights shake which makes the car seem junky. i need this fixed bad!

like your head lights get dim? does the head unit shut off then turn on? or is your car just trying to shake it self apart?

if its getting dim and the head unit is turning on/off i would have your alternator checked. other then that idk definitely check the icv though.

could be a sticking iacv!!

nah nothing gets dim it just shakes it self bad, you know like when you let out of the clutch and it stats to die it shakes.

i thought it was fuel but i guess i can understand iacv. some idot told me engine mounts. that was WRONG!!!

its your IACV

also check your alternator and your relays

bump iacv was cleaned less than 1,000mi ago,before the engine was even installed.Im thinking my prob could possibly be related to the alternator since my lights get brighter if i rev to 3,500rpm and get dim once i come down from that

knoxcivic

thanks for the replys guys!

Try cleaning out your FITV. Not sure if it would cause the problem when the engine's warm, but it's still worth cleaning. It's just as easy to clean out as the IACV and certainly wouldn't hurt to do anyway.

And even though you cleaned the IACV, as wrenchez81 said, it could be sticking.

knoxcivic is your check engine light on? What year is the motor? what type and year is the ecu?

knoxcivic

no check engine light, it's a 98 h22, i dont know about the ecu but i was told it is the appropriate for the car engine swap. car runs strong it's just when it stops.
