Hey all,

I figure this is a computer problem but I don't know how to remedy it! I just installed my new stereo and I had the battery disconnected for a short period of time.

The car now idles at 750 and dips to 500 (labours a bit) then goes that to 750. It does this whenever I disengage a gear.

How to I teach the computer what idle is? Its an 97 EL XR6

Thanks!

I think your supposed to just drive it a bit.

the computer relearns over time....

after a week or so it should be rite...

there is a procedure that you can follow to re-calibrate it straight away...but im unaware of it...perhaps somebody else knows??

It goes like this.

Engine warmed up idle for 1 minute under the following conditions:

1. Neutral with all electrical loads off
2. Neutral with air-con on
3. Drive (brakes on ) with all electrical loads off
4. Drive ( ditto) with air-con on.

Takes 4 minutes.
don't touch the go pedal during this process.

And touch your head and rub your belly at the same time? :) hehe.. joking :)

Thanks! I'll give it a try tomorrow!

Didn't work. Infact its gotten worse.. it dips below 500rpm now and if the lights are on, they dim!

Argh! Can anyone help?? Do I need to adjust idle screws or unplug and plug something back in??

Same thing happened with my old EL XR6 after the battery had been disconnected for a while. Just drive it normally and the idle should come good shortly.

That procedure is in the workshop manual, worked OK for me the one time I tried it.

It's supposed to idle around 700. I would check your earths.

Check the battery voltage, should read around 12.5 at rest, and 13-14v while engine running. If it was going OK before you disconnected the battery, the fault must lie there somewhere.

Or like everybody else said, just drive it for a while till it re-learns.

Let us know what happens.
