missing on a cylinder or two
Does anyone know what would be causing my engine to miss,maybeon 1 or 2 cylinders?I have had the problem before,twice in fact,the problem being miss-fire in the plug leads,thinking this was the problem this time, i replaced them but to no avail.Could this be the coil pack or could it be injection problem.N.B.On examination of the plugs N0 5 appeared to be wet.
the leads break easy when pulled off that cause missing It happened to my vx Ecotec
so try replacing leads and plugs that fix it on mine
When I say No plug is wet it seemed to be wet with unburnt fuel which leads me to believe that there is a lack of spark on cyl no 5.Originally Posted by holden123
Missfiring is not uncommon in ecotecs so start checking simple things like replacing your plugs and leads first. If the problem is still there then id look at replacing the coil pack for cylinder 5 and then dfi module (alloy plate under the three coils)
LOL!
if it's definatly 2 cylinders it's the coil pack for the 2, if it's one it's a lead or a plug, had this happen in my ecotec not too long ago
