Guys i have an idle problem that i cannot figure out,

Do you guys think its safe to boost anyways?

 

get the car running normally first... then do anything else

 

depends on what your idle problem is. if its somethign as simple as a bad cold idle valve that makes your idle lopey it shouldnt matter much. more info.

 

im not sure what is causing the bad idle

 

check for vac leaks

 

Little more explanation of whats going on with the idle please.

 

My idle fluctautes on cold startup, about 500-1500rpm.
When it is warm, does it about 850-950ish rpm.
You can hear it surging.

Put on a different Throttle Body
Installed a Walbro Fuel Pump
Intalled a Aeromotive FPR.
Used Another IACV.
Changed Fuel Filter
Changed Plug Wires
Changed Plugs
Vaccum Hoses are good [used carb cleaner on them]
Tps is set to .45 Closed Throttle
Used 2 Other Stock ecu.


Please help me fix this guys

 

Sounds like a vacuum leak, you try looking into the fast idle air valve ?

 

Dont got one of those FITV under my Tb.

I sprayed water all over the engine bay and didnt notice much

Thanks for your help so far

 

what are u tuned on? crome? i heard that tuning on crome could cause a little surging idle like that? correct me if im wrong. just what ive heard.

 

It could be a leaky intake mani gasket, tbody gasket.

 

im not boosted as yet, i will be soon....

ahh well that throws my idea out the window!

 

This is what i did,.....


sprayed water from a water bottle arround the engine,
i did not notice any difference, also could be that my exhaust is too loud.

Tightened up the nipple/vaccum fitting from my aeromotive fpr , re tightened the intake manifold bolts... top side only.
and took out the pcv valve, and blew both directions on the valve.

I heard a very slight rattle from the pcv, im not sure if its supposed to rattle more?

Now upon doing that, its noticeable less surging...

what you guys think?

 

can injector o rings cause a leak?

i have noticed one of my injectors have a hair line crack

that's where my vac leaks were....all 4 of them had bad seals

 

thanks buddy

 

was it the top seal or bottom seal?

bigger or smaller?

 

also can a big exhaust leak cause that problem?
