92 Integra Idle Issue, new info.
I've been hunting this ------- problem for months.
Fixed FITV, IATV(EACV WTF), PCV, TPS, checked for vac leaks numerous ways, numerous times.
So Yesterday I decided to throw on my boost gauage and see if it will show me whats up with the vacuum.
At idle, vac is about 14-20hg cold. When warm it fluctuates from 14 to 10. When cruising, it is steady, depending ont he rpm, generally around 20hg.
All of these numbers are approximate, and the gauge is hooked up to my fpr.
So does this help anyone tell me wtf is wrong? I guess I have a vac leak, but how large is it? I looked everywhere, pinching tubes did nothing, spray tested.
Anymore ideas?

Re: 92 Integra Idle Issue, new info.
vac w/ stock head/cam/pistons/compression ratio etc should be around -20 in
sounds like a leak somewhere or low compression in 1 cyl. bust out a compression tester.
I think i have a similar problem w/ my car, but today i noticed a pronounced ticking from one of the header tubes. bad valve i guess, o well the sucker still runs.

damn, ***, etc.
Compression tested good with this leak about 2 mo's ago, cant hurt to check again.
I checked the im and tb by spraying a mist carb cleaner and seeing if it got sucked in, then hosing it own and seeing if the enginge responded...nada.

Looked some more today. 20hg vac when in gear and not pushing the gas pedal, also when in neutral and cold. Also once I am moving at a good clip its at 20hg, so there are no problems. Only thing is hot idle = 18-14hg or so back and forth with the rpms...so def a vac leak I guess.

Re: 92 Integra Idle Issue, new info.
Both of those are true...vac leaks are gay. All I know is that its at 20hg when I am cruising, idling cold, or rolling in gear.
I'll keep an eye on it on my way to the junkyard today and let them ****** know. Or something. thanks for caring.
