k all the wiring is correct and done. the vacuum lines are all connected. it starts right up but it idles super high at 5000rpms . i tried switching the tps wires and nothing happened still the same. i'm using an 89 integra TB cuz the manifold didn't come with an Si TB

also, the manifold has a solenoid thing at the back i think its the fast idle valve. is this the problem ? do i need to hook it up ? wire colors are totally different from the dpfi fast idle plug

replaced int manifold gasket with new one.

can anyone help me! i'm thinking its most likely the TB cuz i did the mpfi swap to my first car and it did the same thing and i thought i left a vacuum line off.

*i posted this in the EF forum but i'm not getting many responds. please help!

anyone ?

k here's the update! i started it up again and unhooked the eacv plug and the idle went down a little. i did this because i don't wanna ruin a perfect running motor so knowing that if i unplug the eacv the idle will drop so you can adjust the idle but even after i adjusted the idle. it still revs at 5000.

get this. i sprayed carb cleaner in the TB and the idle went down significantly then went up again real quick!!!

is it a vacuum leak or the 89 integra TB ??????? someone help!

what was the matter, where on the throttle body. im kind of having the same problem??

When you spray carbon cleaner in the throttle body it will bog down for a few seconds. It isn't the most flammable liquid, it's designed the coat the carbon then the combustion chamber burns that.

BTW, what did you change? I am VERY surprised that no one responded...

i sprayed the carb cleaner into the opening of the TB. but it doesn't matter anymore i figured it out myself. stupid TB was the culprit all along and i had a whole Si motor/tranny in my other car and all i had to do was change the TB...damn!
