if you search you'll find instructions on grounding the ECU and adjusting the idle screw

If u dont ground the TEN terminal in diagnostic connector, you will not be bale set the base idle correctly. it will be like chasing your own tail as ECU compensates for any changes you do to base idle without grounding TEN.

As above, the correct way to do it is to connect GROUND and TEN before turning the idle screw. I posted an alternative (read: wrong) way to do it in another thread and got into an argument about it with Cosmo, who was right the whole way through. It did work but it was completely the wrong way to go about it, so I've just found the thread and deleted my posts there.

Sorry Cosmo, I was a noob

He must have connected B+ to GND!! (can happen as TEN & B+ are right next to each other), which can draw up to 10A of current and melt all insulation and plastic bits.

Mine idles at 2000 Then after a few seconds drops Under 1k

BULLET · 02-10-2009, 01:21 AM

Yeah well thats what it did but not it just stays at 2000 and even when the car get hot it stays there and maybe sometimes it changes but mostly there.

Depends what sort of a damage its done to the wiring. All those wires directly connected to the ECU through main harness. If its just the plastic box damaged , then you can replace that with another one from another astina . You may still have to do some soldering to join wires. Hopefully your ECU is not damaged by this accident !!

I wanted to change mine but it looks like it's part of the loom with no conector plug. If you can't patch it it's going to be a pain changing all the wiring.

The book says
1 Throttle not closed, check if it's being held open, force it back to the stop.
2 Idle speed control malfunction
Air valve not closed
ISC valve stuck
ISC valve connector disconnected
A/C P/S or E/L signal sent to ECU
Incorrect coolant temp signal
