Hi All,
I have the 5.7L Excalibur motor and had a couple of dramas last weekend.
The motor sounded as though it was misfiring at moderate rpm. Power was ok up until this point. Not really knowing where to start, we removed all plug leads and reconnected. This stopped the miss fire and all was close to normal.
The only thing left over was a engine shudder or rough running just above idle then it appeared to disappear or get lost in the higher engine rpm after this. This is on acceleration and deceleration. Power is sill good. I can hear what sounds like a burbling/missing noise in the exhaust as we come off the plain which is not normal in the past.
As a precautionary measure, I have ordered a new set of plugs and leads since re attaching these seemed to eliminate the original misfire problem. Is there anything that this original misfire could have damaged.
The shudder I am chasing now is not that obvious but I know it was not there before the misfire issue.
Thoughts?
Andrew
