JGTTDI2 Posted July 23, 2012 Report Share Posted July 23, 2012 (edited) Please help, got a seat arosa 1.0 mpi with an engine misfire, I have changed the egr valve, spark plugs, ht leads, and cleaned the throttle body and fixed a slight split in the intake hose, I'm fresh out of ideas, the car idles fine but any throttle at all and It drops a cylinder or 2, it is unsafe to drive due to constant misfire under load, could it be a valve dropped?Please please help, thinking of setting it on fire!

JGTTDI2 Posted July 23, 2012 Author Report Share Posted July 23, 2012 I will try the main coil, do you think that would cause it to misfire under load?Thanks Quote Link to comment Share on other sites More sharing options...
