Hi all

My Saph 4x4 Cosworth was overheating due to sticking thermostat so I'm currently running it without one...

The car now misfires badly as soon as it comes on boost - i'm thinking that this is possibly as a result of the ECU reading a cold engine temp (temp gage is now generally much lower althoug it is in the 'norm' band) and overfueling to compensate...

Is this possible or is it more likely to be something else?

Thermostat is on order so i'll get it in next week just wondered if i have more problems though..

Thanks in advance,
Boon
