Cold start idle issue

That does just codes though???, it would be good idea to get one that reads live sensor data as well, so that you can get fuel trims and Oxygen sensor outputs.

Hmm, got the code reader but says no codes! Frustrating. On to one that does live data too like sambomonkey says

Can highly recommend a scangauge2, got my mounted on the steering column.

Looks like a good bit of kit but a bit pricey for me I think

If i hold the throttle down for a brief second upon starting and let it out gently it idles fine. However it has to really watm up before it doesnt die out when the revs drop quickly, such as reversing out of the drive and coming to a stop/coming to the end of my road.

It does run on lpg but that shouldnt affect it as it starts on petrol until warm.

Any thoughts appriciated!

Does anyone know if the throttle position sensor would affect this? I have read about resetting it by turning on the ignition and pressing the throttle a number of times? If this is actually a real option, would resetting this mean the ecu is reset? If so would it ruin the re map that was done after the exhaust and filter were done? It's showing 204bhp at the moment so don't want to ruin that....

I don't think you can do a tps reset on the v6.

Sorted at last. And it turned out all it needed wad a load of carb cleaner sprayed into the throttle body. Starts and idles perfectly now without throttle being applied.

Thanks for all the help along the way. Wish I had done this first instead of last though!
