Got an 00 jeep grand Cherokee 4.7 v8
It is throwing p1756 p0300 and at least 3 diffrent misfire codes for cylinders always different and every cylinder has been pulled
First I noticed really bad exhaust manifold leak causen the H02 sensors reading unmetered air. Extracted the broken bolts
Nothing still doing it
Did compression test getting. 90 - 100 all away around
replaced cam and crank sensors
Still nothing
Any ideas whay it might be
