help! - cylinder 3 is dead.

ok, i need some expert help here guys.. please.....

 

cylinder no.3 [back left as you look at engine] is dead. ive tried a new coil/changin coils around , ive also tried a new spark plug and tried changin them around. so it appears to not be one of these faults. the car has no other problems except this no.3 cylider is dead - and also it cuts out some times and stalls ?

 

someone has suggested that it may be the PTU that is not operating properly - does anyone think this may be the case? does anyone have one that I could borrow/buy to test if it is the PTU? or does anyone have any other ideas what may be the problem?

 

im goin to get my garage to do a compression test this week aswell - but apart from this - i lost - i dont know what the crack is!

 

help............Ben.Leicester.down and nearly out.
