i got a problem..i have a b18 in my crx..and it idles at 2500 ..and when the motor is cold it idles up to 4000...i check for vaccum leaks but theres none can some help me

 

Have you checked the EACV? Could be a crack vacuum line or bad intake gasket on the throttle boby or at the head. I changed out the EACV on my D16 and it fixed it.

 

dude, it is your TPS sensor(throttle position sensor) i bet you it is bad.

 

vacumm leak wouldnt cause it to idle so hight, it would make the idle fluctuate

yea i think its my TPS. i checked today and it flashed code 7. but i check the blade in the TB and its closed all the way..how does the TPS work? does it tell the ecu how much fuel to pump?maybe im running rich. how do i fix my TPS

 

if your tps is riveted to the throttle body, remove the throttle body and drill out the screws. then replace the rivets with screws. put the throttle body back on the car with a new gasket, and start the car up. loosen the screws enough that the tps can be turned from side to side, and move it around and check the car's reaction. it should help a bad idle. if you have a dashpot on the front of your intake manifold, remove the vacuum lines to it and plug them all up. how is you map sensor hooked up?

 

if u just swaped the B18, maybe u forgot the swap the outer TPS cables whern doing DPFI to MPFI...
if u had the car fine and started doing it , then ur TPS sensor went bad.. and u need a new one.......

 

i have an HF so didnt have to convert to MPFI...when i first stared the car after the swap it would idle at 1000-1200 then like a week after it went up 2500..where can i get a new one and how do i know if it is good or bad?

 

ttt..help
