i got the exact same problem...

bump

 

bump for some more answers.........

 

HAVE THE SAME DAMN PROBLEMS!!!!!!! BUMP let me know if you find out whats wrong

 

I idle problem too. The idle just drop and went back up. I try to adjust the IACV and no luck. I talk to my tuner about the problem. He said that sometimes the o2 wen bad. My tuner switch my ecu to run on open-loop instead of close-loop. Have your tuner to set it run on open-loop. Try and see what happen.

 

open loop is when your not throwing any codes i believe...

yeah i replaced my IACV to.. nothing.

 

talked to local tuner and said that tuning and switching the map sensor to a 3 bar one should take care of it... Or maybe switching to a 2 bar set up. O well it's going to the shop for tuning and dyno on monday

 

bump for some more ideas....

 

ok, i did a compression check now too, it's 185 on EVERY one of them...and it holds the pressure with no drop until you release it on the tester......also, i ran it on a cooler night last night, and it ran PERFECT the whole time? if this is how it's working wouldn't it be a tuning issue?

 

If you have a hondata gasket....be sure your intake mani bolts are tight, used with lock washers....sometimes the bolts back off...leaving a vaccum leak thru the gasket....also be sure your injects are fully seated...coulda came loose...

yeah ive considered pulling my intake manifold off and putting a new hondata gasket in there.. but putting those JG manifolds on is a ****

would a leak of that nature throw a code?

so no one has any ideas of what the problem could be?.....could it be the settings for fuel enrichment in crome? for IAT sensor readings?

the way i check for vaccum leaks is i pull of the intake tube and then block off the throttle body with my palm.

then engine will suck ur hand in,

then the car will stall cause ur stopping all the air from going in.

if the engine keeps running, u have a vacuum leak.

 

what throttle body do you have obd 1 or obd2?
