so me and my buddy just rebuilt the engine on his integra GSR. everything went back together fine but when you turn on the car, the idle jumps between 800 and 2G's over and over. what could this be? we have gone over every single connection. this also only happens once the car warms up.

russiankid · 03-01-2009, 05:18 PM

Did you bleed the cooling system properly?

MTuning · 03-01-2009, 05:21 PM

idle problems on hondas can be alot of things. a common mistake when putting it back together is using the wrong plugs since a handful are alike and FITS multiple sensors. the ECU kicks in when its warmed up and starts reading sensors but not getting the correct readings. If everything was running fine before and NOTHING has changed than i would go over the electrical stuff. Honda's are picky on grounds too. make sure all grounding are where they are suppose to be or atleast grounded.

russiankid · 03-01-2009, 05:38 PM

Doesn't the ICV have coolant running through it on the B-series as well?

superskaterxes · 03-01-2009, 05:41 PM

hmm we will have to go over the car better. he did just beef up the grounding system so its prob not that.

and what does the coolant have so much to do with it?

Spocknasty · 03-01-2009, 05:45 PM

Clean your IACV screen and check your TPS. My D16 used to do that.

I wasn't sure if the ICV has coolant running through it or not. If it does, an air pocket will throw it off. I know it does on A series motors.

superskaterxes · 03-01-2009, 05:52 PM

he said he cleaned the IACV screen and the TPS was fine. keep em coming boys

james_ls · 03-01-2009, 08:18 PM

Proper ECU?

2001teg · 03-01-2009, 08:27 PM

Double check and bleed the cooling system again.

MTuning · 03-01-2009, 09:34 PM

dumb question but timing was aligned properly on cams and crank? IACV and ECT has the right connectors on? they're the ones that gets mixed up. it could be the tps off calibration but that shouldn't of been off. there is coolant going through the IACV but is it overheating? what year is the motor? does he have the crank angle sensor? chipped ecu or stock? are the grounds in their stock location? checked for vacuum leaks? any mods?

driftingrx5.7 · 03-01-2009, 09:37 PM

i am going with IACV or bad vaccum leak

dubjinc · 03-01-2009, 10:42 PM

Mine did this when my primary O2 and tps sensor threw codes.

he bypassed the coolant on the IACV. its a 95 b18c with 140k on the clock. no crank angle sensor. its got a whole new grounding system and no vacuum leaks. its got intake and CBE.

brand new O2 as well.

ill report back tomm guys after some more checks and coolant flush

sundaybikes · 03-03-2009, 08:24 PM

you sure no vacuum leaks or clogs? my b16a2 surged like that and it turned out a vacuum line was a little kinked or disconnected or something.

TurboGSR96 · 03-05-2009, 09:59 PM

Why did he bypass the IACV? Hook it up the way Honda had it, make sure there is .50ish volts at the tps with the throttle closed and around 4.5 with it fully open. If it has a FITV take that off and clean the inside of that too along with the IACV.

superskaterxes · 03-06-2009, 12:00 AM

whats fitv

Dlaub25 · 03-06-2009, 05:22 PM

The FITV was the problem with mine. Its mounted on the bottom of the TB. Should have 2 hoses connected to it. Its what the holes on the inside bore of the TB are linked to. (well I know at least one of them is). I wound up getting a block off plate from KMS. It looks pretty nice and it solved the problem. What the FITV does is allow extra air to bypass the throttle plate on cold starts. I have been fine wiithout it in 0 degree weather.

highmilehatch · 03-17-2009, 09:13 AM

Why would you bypass the coolant on the IACV??????

Sounds like your problem right there.

And throw that stupid grounding kit in the garbage. They do nothing but clutter the engine bay.

I'd have to agree . .

Or a vaccuum leak somewhere
