stalling? dont know if its a major problem, or a easy fix.... 89' VN

[mike49]

hey guys, i have a 1989 VN exec, stock V6, HSV5000 chip (apparently)

and i notice when i give it a quick rev, when it goes back down to idle, it goes down to about 0.200rpm and then stalls. then it takes about 4 - 5 seconds of the motor turning over for it to start again, it goes fine, heaps of power, spins the wheels all the time (accidently), its just this one little problem thats got me stoked.. any ideas?

cheers
Mike

idle air control on the throttle body
doesnt let enough air past the butterfly when the butterfly is closed

if you have a HSV5000 chip, i assume is for a 5ltr v8 and you have a v6 so that might be a problem?
But seriously i think it is your Idle air control valve. Disconnect the red wire where it goes into the bottom of the engine fuseable link, leave it off for a couple of minutes. Reconnect it, then rev the car to 3000rpm for 10seconds you will see the revs drop a tad. The IAC should be reset. Its a good idea to let the car warm up before disconnecting the fuseable link.

cheers for the replys

and yeah apparently its got a HSV5000 chip in it, but it was a family owned car, and ive driven it when it had its stock chip, and now with this chip, well you can feel the difference!!

it should have the SV3800 chip for V6 HSV5000 is V8
