Hi i get my car back today and because the warranty wont cover coils i need to check and see whats causing the lumpy misfires i occasional get b4 forking out sh*t loads on new ones. ppl say check the maf...can someone pls tell me what and how i check it? unplug it? cheers

 

the maf on your car is rock solid and unlikely to be the problem.

coilpacks last about 80k and 4years and are worth changing if you haven't etc..
