99 3.9 #4 CYL MIS
I know, old topic but-could a plenum gasket cause a complete mis on #4 and drag #3 down about 10 misses a minute.I have good fuel pressure-spark-compression etc. Pulled inj. and check spray pattern-good. Leak down test on cyl was good. Switched cam and crank sensors from other vehicle-same.?? Intake does show some sign of oil leak but not a puddle. ???????????????????
