More than likely your power latch relay is hosed. It keeps the power to the computer for a few seconds after you turn off the key so that the computer can reset the IAC and be ready for starting the next time.

Hey no bad mouthing Renix. Some of us like them. It's like being married, once you find out what the quirks are, you can learn to manage.

X2 they are $7.50 at Oreilly auto here in KC, IIRC it is the one closest to the firewall.

Those 4 blue relays in the pic. Just take the front one and switch it with the back one. IIRC dont trust me on that though I think that the front is the AC and the back is the Latch relay.

Re: Renix 1988 hi idle at start up

yeah I know old man.I DO like my renix system,hell I've tuned it in by timming adjustments and air/fuel ratio tunning as well,my timming is electronically adjustable with a timming box for Chevy LS1's go figure,well anyways my ONLY problem is with the idle circuit,IF I were only electronically smart enough to de-bug that part of the pcm.....I'd be a millionare!!!!!!! as I have searched this deal a LOT and it is just a design flaw,from what I can see/read is there are a lot of renix owners out there that can't get rid of this issue either.Just tryin to find out what other people have done to resolve there idle issue so I can try what others have done to fix there's IF they have that is...................
