Idle problem NA

My NA 1600 has developed dreaded idle creep. I have tried the GRN/10 bridge, no luck. The idle screw is now fully down and still idling at 1400 revs. Have sprayed Aerostart all over hoses, no change. Any ideas?

Maybe a vacuum problem?

Have you checked the ignition timing setting & other settings? Also disconnect battery, pump brake pedal a few times, then reconnect battery to clear ECU. Here's some more detail on setting idle when there's an idle problem: viewtopic.php?f=76&t=60434

^ that link has good advice. I just about went through each one of those items in the list without knowing that such a list existed!

There are so many possible causes. Mine had the same issues as yours (idle at 1500rpm).

I had a cracked crossover tube, bad injectors and bad ISCV. Cleaning the ISCV helped, but it wasnt until it was replaced that my idle was OK.
