Ok just yesterday and today the cossie has be playing up Not surprised its nice warm weather and its goes tits up All the crap weather she was going well

Right then ;

When i have been driven it OFF boost for say about 20/30 mins or so its starts playing up,
I go to put my foot down and it splutters and pops and Banges ALOT also the Rev gauge jumps all over the place It was getting worse ans worse so i go it home and have left it

When ever i have been driven it hard it seems to have been FINE
Could this be a sencer breaking down like the one in the dizzy As this one has been replaced once as it would'nt start ect due to it

Ps its been over fueling for a bit And also has a missfire which has been p!!sing me off a bit as i have tried every thing i can think of
When i got the car is was running very poor and turns out the CAM BELT was 1 tooth out on one of the vernor pully so it may have damaged a value or some thing (have'nt removed the head yet) could this bee the missfire ???


Any help ??? thing to look for ???
