so i got this strange misfire after I smelled oil and now car only runs on four piston (1-2-3-4) passenger side, (5-6-7-8) runs weak barely a diff if i unplug 5678 so i checked compression , new plugs proper gaps ,, everything main relays but at WOT it doesnt seem misfire and sounds like its running on all pistons , I checked voltage on the COP'S harness they all got power.
OBD2 Reader tells me Leak at egr and sticky injector on piston #7 and dirty MAF but cleaned it with no noticible cure,
car is stock but gutted the CATS
I did clean the injectors two months ago so I figured the injector for cyl 7 could be completely dead? and obd tells me only 7 is missfiring but it clearly only runs on only the fours on passenger.
Could the egr be stuck open or closed that might cause the whole bank to miss ? cause if only #7 is missing it wouldnt missfire that bad IMO
i even swapped the four cops on other side and same thing they run great on passenger side bank but not on the driver side.
major miss at cruise and idle WOT sounds like all of the dead side getting power but less power.
