Misfire on cyl 4

Recommended Posts

My issues started about 6 mos ago with issues starting occasionally. Engine would always start but seemed to crank excessively. Well the other day when on a road trip to visit the family it started to shudder while accelerating at around 3500-4500 rpm. Then I got a misfire code. Replaced sparkies and coils since it is at 150k miles already. Problem still occurs. Threw some injector cleaner in with no expectation it would help. Fuel pump has been tested and it’s within spec. I have a dealer appointment Friday but I’m supposed to drive back home Monday. It idles fine but it’s when accelerating hard it becomes problematic. It also feels like there is some resistance when accelerating in general but no misfires. Not burning coolant or oil so doubt it’s a head gasket issue.
