getting code 32 lambda sensor would this cause me a boost prob and a bad missfire on boost plugs and coils been changed?

right then, the lambda on your car is only used on light throttle for controlling the fueling, once you go past quarter throttle the map in the ecu takes over and the lambda isn't used.

this means the misfire isn't being caused by the lambda.

you say you changed the plugs and packs, did you use brand new packs or 2nd hand?

also what plugs did you use???

pfr 7 plugs coilpacks from a friends car which is running fine would a faulty cam sensor cause this

the cam/crank sensor could cause this type of fault but usualy they will chuck up a check light and store a fault code.

i have seen this type of fault with a dodgy maf sensor where it would hesitate just when coming on boost but had no fault codes stored in the ecu.

are you running a boost gauge??

the reason i ask is it could be fuel cut if the boost is creeping over 1.05 bar, if not i would be looking at swapping the maf from your mates car to see if that solves the problem.
