I installed a Brand New Skunk2 Intake Manifold on my 2000 Integra GSR. Went to go start the engine and it idled around 750 rpm(COLD) and slowly dropped until it died. Idle does not fluctuate. Sometimes it'll starts and idles very low around 250rpm maybe lower and sometimes the engine wont start at all. It was running like a champ before the Skunk2 Manifold installation. I've checked all vacuums and coolant hoses and they're fine. I swapped the stock throttle body along with the TPS and MAP sensor which were untouched. Maybe I did something wrong. I'd appreciate it if someone can help me out. Please.

 

I was reading another post on here, wish i had a link to give you. But I remember reading about the butterflies in the original intake runners and he was having a lot of trouble with vtec. Everybodies answer to him was to get it tuned. Your ecu still thinks the intake still has short and long intake runners. Thought I would share, good luch searching

 

Spray carb cleaner all around where it meets the head, t body gasket and vac hoses. When the idle jumps up you found your vacuum leak.

 

i dont believe that it is a vacuume leak, after doing a modification like changing your manifold to a high flow manifold you will need a tune. not saying thats the only problem but probably a big majority of it

 

U don't need it tune.. I've install 3 of those already and it's all good.. Check the ur tps and map sensor.. Could possibly wrong connection.. Could possibly clean out ur iavc.. GL

 

That doesnt make sence because he has all the same sensors and it didnt have the problem before.

 

I think he ment op might have switched the connectors around.

 

just for the record, what does op stand for. also, I have ran into that with the tps and map plugs being switched. It idled fine, just would rev correctly. Eather way, I hope its an easy fix. good luck

 

No. The car won't have vacuum leak symptoms from installing this manifold.

 

haven't checked yet but i think it's a possibilty i've might have put on the throttle body gasket on wrong causing the gasket to block the port that leads to the IACV which controls the idle.

 

OP= Original poster, the guy who put up the thread.

If that's the case then you should loudly hear the leak. How's your coolant temp? Put up a picture of your setup. I need help on how to route the coolant lines and PVC hoses.

 

throttle body gasket is on correctly. i knew i couldn't have put on the gasket wrong. i'll post pictures when i get a chance.

 

If you are still using the stock throttle body, what did you use for the throttle cable? Did you get a type-R cable and bracket? I would test the IACV first and confirm that it is working properly.

Does the engine rev up? can you hold it at 1000 RPM? If it does, do a check on the idle. it might be outof adjustment for some reason.

 

it wouldnt need a tune to keep idle just from switching the intake manifold. something isnt installed right. take it off and reinstall. during the process you may find where the issue is coming from

 

i re-used the stock gsr throttle body and gsr throttle cable bracket. worked out fine.

 

Are the iacv and iat connectors reversed? They're both 2 pin.

 

going into the manifold swapped i knew the two connectors were similiar but i noticed my tps connector is a blue connector and the map was grey. so thats how i know distinguish the two connectors apart. still nothing. going to pop the IACV off and clean it see if it does anything.
