mpfi swap done but idles at 5000 rpm!!
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!

Re: mpfi swap done but idles at 5000 rpm!! (zcivicz)
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!

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...

Re: mpfi swap done but idles at 5000 rpm!! (w00t!)
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!
