Misfires

(1/1)

Gts556:
Hey guys. Kinda stuck on this. Having changed 4 injectors, pcv kit, coils plugs, maf sensor my car still shakes on idle with a cylinder 1 misfire. Thinking to take it to r tech to maybe get this sorted? Any suggestions ? Thanks!

mjmallia:
Did you carbon clean the valves when the injectors were out?

GVK:
Doom and gloom - Could be a broken piston/ringlands - leak down and compression test required.  :scared:
