The best place to start would be to get the car on Tech 2 diagnostics at a Vauxhall dealership or get a mobile mechanic with the diagnostic software out.

There\'s so many sensors along the way that could be causing problems, ICV, AFM, Knock sensor, CTS, etc and it might not even be any of them!

The V6 is a great engine just make sure it\'s got a lightened fly wheel, this will make the most of the engines power.

what BHP are the v6 motors against the 2L 16V which is better been told the 2L valver is better ? but v6 sounds nicer lol

what are the 2.5 v6 corsa\'s selling for on L plate its ment to be a GSI in grey with 17\" on and full black leather ?

thanks

C25XE (V6) 167bhp

C20XE (Red-Top) 150bhp

Remember the V6 pushes out a lot more torque, but the red-top is lighter.

As for retail value there aren\'t many V6\'s Corsa\'s for sale so the price varies dramatically on the quality of the engine transplant.

got the corsa, the motor fires up first time and ticks over ok, a bit lumpy tho? ECU light is on all the time then sometimes flickers off for 20 ODD seconds then comes back on the car revs up fine, but sometimes back fires through air box ? sometimes on tick over the motor hunts alot and sometimes sucks air more?

any ideas ppl ?

oh ABS light is on 2.

p.s how do i get my rev counter to work

The ABS light will be a wheel sensor.

Change the coolant temp sensor, this is located near the underside of the inlet manifold. Do the paper clip test on your ECU to find out what the fault is. try www.topbuzz.co.uk for more info.

going to do that test tomora,

would that sensor make it run lumpy from cold tho ?

thanks alot for the help btw

The Coolant Temp Sensor (CTS) is the ECU\'s way of knowing how hot the engine is.
