Spark plug lead had come off module
Hi everyone i'm new to the forum..
This is my 2nd crossfire and I've never had any real issues with either car.
However I was under the bonnet today just checking fluids etc and I noticed one of the spark plug wires had come off the module its ment to be connected to.has anyone else had this happen?.
Also as silly as it sounds would this have had affect on the performance?.
Had no EML showing and no codes when I connected my tester.
Cheers all.

It is not a know issue, I would think it would somewhat effect performance as the engine is most efficient when both plugs are firing.
Ever had flight lessons ? If you have, then recall the mag check :
Engine turning at 2000 RPM with switch in both, turn to left only and see about a 200-300 RPM drop, same with switch in right only position.

they don't fall off themselves as they clip/snap the connection. whoever worked on your car last accidently left a wire loose from your coil pack. have you had a tune-up done recently?
each cylinder on your car has 2 spark plugs, they take turn firing first as they alternate back and forth, so it fires a then b on one cycle, then fires b then a on the next. so you still have combustion, just retarded on that cylinder half the time. The other time the extra unburnt gasses go out the exhaust, or rather in both cases.
