I have a b18b swap in my 91 crx si obd1 conbversion and i can not get ti to idle higher than 400-500 rpms I turn the idle screw up and it does not do any thing

 

bump

 

adjust the small screw on the TB that is underneath the plate that the throttle cable connects to

 

Any vaccum lines off?

 

a vacuum leak generally causes the car to idle high

 

Maybe in some cases if does but in some it doesnt. I have a line off and my car didnt want to idle.

 

I tryed to turn the screw but I can not NOT get it to go any higher than 4-500 rpms , I have my charcol canister removed and capped off

 

are you running anything aftermarket? (cams, valvetrain, ecu chip)

also check your valve clearances and make sure all your vacuum is hooked up correctly

 

I work at an acura dealership and the idle adjustment screw does nothing , they want you to think it does but it has a sensor or a valve that u have to replace . Not possitive but def something to look into ........New to HT have a DC2 built pics up asap throughout the build

 

were would this sensor be located at?

 

I was able to get it to idle a little higher by moving the distributor towards the bumper a little which it was in the center is it bad to do that?

 

Yes, you just blindly adjusted your ignition timing, so who knows where it is set at now. You can make it run like a charm at idle that way, but now who knows what your timing will be at when you are higher in the rpm range. Use a timing gun.

Have you checked to see if you skipped a tooth on your timing belt?

 

NO I have not cheacked it with a timeing gun, I need to but what other way can I fix the idle the motor just has normal bolt ons?
