hi guys, got a problem with my 99 12v, starts fine and drives fine for about 20 miles or untill engine is hot. once hot it intermitently hesitates when pulling away kinda like a faulty maf does, although this has been changed. Had it code checked at a garage and they couldnt find a fault code. also they cleaned throttle body and idle valve etc. Has anyone got any idea what could be causing this???

Possible crank sensor

would that not store a fault code tho?

not always, it would only log a fault code if the EML light was on for 30seconds or more usualy

no light on at all, just stutters and hesitates and then goes but only when hot, no problems with cold at all.

crank sensor where u from mate?

portsmouth mate, they easy to change? i am quite practical.

fitted crank sensor, didnt fix, any other idea's?

Was your new MAF a pattern part or a proper vauxhall bosch one?

Have a read of my thread mate, it may be of help, changed my crank sensor this morning, now i'm sorted.

maf was a genuine part. been code read and found lamda sensor and immobiliser fault. lamda changed. still got fault. not showing ecu light up. what could the immobilser fault be as didnt realise it had one???

could the cat be at fault here?

back box baffles were knackered and that has been replaced, hence the lamda issue, still got the hesitation problem tho
