Hey everybody this is my first post. I have a 90' Acura Integra ls and I had the jumping idle. I just changed the tps sensor and when i started the car, the idle jumped up to 3,000 rpm and stayed there with the check engine light on. Then i messed with the idle sensor and now its down to 2,000 rpm w/ C/E light. I checked the ecu code and it blinked 7 times then stopped and then blinked 7 more times. so the code is 77. I googled the ecu code 77 and didn't find anything.

Can anyone help me?

Thanks!

 

check the iacv maybe it needs to be replaced.

 

whats the icav? We got the idle down to 2,000. I tested out the map sensor from my friend's 92 gsr and it still does the same. So we ruled out that it wasn't the map sensor. We pulled out one of the vacuum hoses and the idle went down to normal but when he put the hose back on.... it jumps right back up. Could it be a vacuum hose? Today we're going to try a different throttle body.... that's the conclusion we came up with.

any other sugestions?

 

You sure that code isnt a code 7 for the tps sensor? I would try replacing the tps or getting it checked out.

 

Iacv is the Idle Air Control Valve. its usually located behind the intake mani. its got two hoses plugged into it. one coolant and the other is a vacuum hose i believe.

 

Well the tps is fine now. Yeah the ecu code was 7 and all i had to do was move the tps sensor a little bit..... I'll check the iacv... any way to test if the iacv is still good or should i just replace?

 

well i cleaned my iacv with carb cleaner. just sprayed the crap out of it. You can try that nd see if it works for you.

 

alright, im going to try that. now i just gotta find some carb cleaner :D

 

ok so i sprayed the iacv.... whats that nut thats on the side of the iacv that is the shape of a pentagon? should i play with that or is that a no no?

 

make sure u dont have a air leak cause when i put a intake on my car i had a leak and it was idled up to 3000

 

whats the best wway to find an air leak? Get dish soap and rub it on the hoses?

 

Hmm, found a crack in the radiator hose going into the iacv..... maybe thats the problem?

 

u can tahe brake cleaner and spray it like where there may be an air leak and if there is a leak it will idle down for a sec.

 

ok thanks for the tip!
