My car has occasional misfire and only boosts .9 bar usualy, but occasionaly spikes 1.4. The misfire seems alot worse if have have got the car wet, im gettin new coils asap, is their anything else that might cause this? Thanks

Sounds like you changing coils anyway. Change plugs while you are there.

 

Ok, is their nothing that powers the coils that may be at fault or is this just typical coil probs
