Was searching through some old threads, didn't really find anything similar. Integra has been having some weird idle issue. Once the car is warm and when I let off the gas or come to a stop and let the car out of gear, the idle will catch at 750, then drop to 5-600 and then bounce back up to 750. I'm not sure what the issue is, but I'm worried the revs may begin to drop too low and stall.

Thanks for any help. Car has about 79k on it.

 

Umm 600 is were your supposed to set the idle to as far as I know. As for rough idel maybe a vac leak some where?? Did it just start happening after you installed something new or just out of the blue kinda thing

 

It's an out of the blue type thing. I think the idle should be around 750, but I don't think it should catch at 750 when the revs drop, and then drop to around 500 and bounce back up.

 

sounds like a computer issue. Maybe the VAFC?

 

Yeah, I'm going to look over all of the setting over this thanksgiving break.

 

I wouldn't worry about it too much, my car goes from 800 to 300 and its not too too bad.
