Valver Problem - Need Help

[BRUN]

when i start the car up in the morning it sits there idling fine, i pull off the drive and as i get down the street it loses a lot of power, i have to hold the revs high or it kangaroo's, after about 20 seconds this goes and its all fine

it only happens from cold starts, and if i dont drive along and just leave it idling after about a minute the revs just start to drop and it tries to bring it back up, more often than not though it stalls

ive changed the coolant temp sensor twice, the ISCV is fairly new, ive changed the throttle body, TDC sensor, air temp sensor, plugs, leads, dizzi cap, rotor arm, and distributor itself all fairly recently

could the cold start injector be causing it to overfuel ?......

i really need to sort this out as its driving me mad, its happened before and i thought it was me messing with the TB but ive now changed that and its still the same

How do you go about that fella, where abouts is it located?

Thats what i suggested

Also give swapping the ECU a go

its had 2 since i got it, one yesterday, all of em read the same values so none of em are faulty

oh the map sensor hasnt been changed afaik, but if that was buggered wouldnt it do it all the time ?

spoke to Nick Hill today and he said it might be lambda, especially if its one of the universal types cos he said they dont work on the correct temp range or somethin, and ive since found out this has got a universal type on it

tried my spare ECU and its not the ECU causing it, as its doing it with that in aswell
