Quick Question about EFI idle...

[festyxfi]

...what's the best way to increase the idle on a 93 Festiva? Working on one that needs to go up a couple hundred RPM's I'm thinking.

I've been messing with 89 carbs too long...

Thanks,
Brenton

There's an idle screw/bolt, but every time I increase mine the computer turns it back down, so I don't know the whole trick.

yes my 89 FI idle is hight on a strait road from a dead stop without giving it gas just the idle it gets up to about 20 mph

Toset EFI Idle
Warm engine...a rad fan cycle or two
Nothing on but engine
Set to park or nuetral
Gound STI Connector
Set idle
Check/adjust timing
Set idle
Check/adjust timing
Should set after a couple back and forths.

Remove jumper

When the jumper is installed...the ECU runs a preprgrammed timing curve and air/fuel ratio.
When you make the timing/idle adjustments...you are adjusting the car to match these preprogramed values.
