Poping quietly at idle and not running smoothly. How do you know if the coils are farked. Link to comment Share on other sites More sharing options...

Say 4th gear going full throttle and it will be fine until the RPM starts to get up a bit then usually a power loss/shuddering feeling. Link to comment Share on other sites More sharing options...

Both can be described as a rough idle.OP are you able to pull codes from the car? Link to comment Share on other sites More sharing options...

Like a lawn mower with sh*t fuel. If you know what I mean. Link to comment Share on other sites More sharing options...
Bomber Carnage on the Garage Floor Donating Members 3,994 Member For: 14y 6m 16d Gender: Male Location: Gold Coast Posted 26/06/15 10:45 AM Share Posted 26/06/15 10:45 AM Had a bit of time this arvo so cleaned the throttle body again as I too had an occasional pop at no load idle. It was grubby around the edges of the butterfly and internally a little. Anyway, pleased to report with a quick clean up with Nulon TB cleaner, the fault is gone.

My mate said it could possibly be the sparks... I pulled one of them out today and they look worn out.. so gonna change them and also the coils and I'll see how I go...
