I just got a 1991 crx si. its stock and i think its idling low. what should it be set at its around 750 now. thanks.

 

750 is perfect...

 

but it seems to shake alot when im at a stoplight that normal?

 

depends on the shake, my car does it but i need a valve job and the distributers cap and rotor replaced. how bad is the shake?

 

it was really bad because the idle was around 500 so i turned it up to 750

 

It might be shaking alot because of your motor mounts?? Not sure but 750 is good maybe alittle higher. Have you checked your timing to make sure that was right on because if its not then you could receive a rough idle. my .02cents

alright i will do that thanks

 

You can set the timing properly by unplugging the IACV and turning the idle up to 750.
