been happening for a few weeks. when driving car will stall, when completing a turn or idling at lights.
revs go up to around 1000rpm then back to 200rpm then it stalls. the warning light on the volt meter comes on aswell. anyone ideas on how to fix it? |

clean up your ISC... it bolts onto the side of the throttle body..

How are your TPS values? Are they sitting on .9v?

Are you running an aftermarket computer or performance chip?
Mine used to hunt / stall when it wasnt tuned properly.

Yeah - I run a unichip too.
In the meantime before you get it retuned, try increasing the idle a tiny bit (adjust the screw on the trottle body)... see if that helps.

i might try that, but will that cure the stalling? currently idles at around 600-750rpm.
increase it to around 800-900 u reakon? if i was to put a manual in it, what sorta power would that free up u reakon? its currently 186rwkw |

A good tune should fix any hunting / stalling issues... but the cheap temp fix is to up the idle.
Manual will have less drivetrain loss, not sure how much though - I have never really played with Auto V8s.

Mate, have a talk to Spiro @ Autotech in Granville.. He'll sort you out. EDIT: Sorry mate, i should have checked your location. Last edited by Bassfreak55 on Sun Apr 30, 2006 7:54 pm, edited 1 time in total. |

gunit - I get my unichip tuned in sydney, so thats not going to be much help to you.
Sorry - dont know anyone in melbourne who does them yet. Someone people say you can run a Manual with an Auto ECU fine. I currently have an auto ecu in my fairmont (manual xr6 running gear), and I find it awfull. Keeps trying to kick down under load, and seems to have lost a lot of power.

thanks but i already got ported gt40p's. was thinking about the manual conversion but then i need another manual ecu.
would i need a manual ecu if i installed say a wolf/ems/motech aftermarket ecu? |

Yeah you would cause transmission is controlled by the standard ecu, which runs all your other electrics etc. You'd need a independant transmission controler but big $$$
I'd look at TPS, that will most likely be the culprit. Put a multimetre into connectors and turn the dual TPS until both read 0.9volts. This is something that mick webb doesn't do cause the holes of the TPS need elongating. This will effect the way your transmission performs as well and idle/hunting etc. Once you know you have done this right, then you can adjust your idleto around 700 rpm |
