Idle Speed Question...1996 2.2 with 1992 ECU.


 

I have this little jewel running sweet. 1992 EFI system running a 1996 2.2 engine with it's own sensors. Have made a VW idle switch do duty as the Idle Switch, missing on the 1996 throttle mounted sensor.

It's bolted to the throttle body, just like the VW was.

So, now to the 'problem'...your notice, this is a 'problem', not an 'issue'....you know who you are ! ;)

Anyway, the idle will take around 25 to 45 seconds to drop to a steady 700 rpm after throttle is closed and IS closes. Is this normal ?

After installing the IS it will idle at 700rpm all the time once it's warm, but during 25 to 45 seconds after revving 2000 rpm and up, it hunts at 950 to 700 rpm before settling at 700rpm. Then it idles steady as a rock.

Any observations ?

And.........dropping into D or R from P or N idle system is doing a great job of keeping idle steady with very little rpm wander during shifting. No hesitation on throttle tip in r return to idle. Does not stall or stagger.

I'm quiet please with the idle quality and this is just nit picking.

thanks
