Asked by Tyler Dec 16, 2019 at 01:09 AM about the 2008 Dodge RAM 1500 SXT Quad Cab LB 4WD

Question type: Maintenance & Repair

I have a 4.7 hemi and I have been experiencing
missfires at random times. I have replaced the
spark plugs, plug wires, coil packs and both
downflow o2 sensors. Same as before with
more horsepower. Any suggestions?

Test the flow coming out your exhaust. Bad callitic convert or cloged muffler could cause miss fire. Think they have a test on the loan a tool at advance or AutoZone. Egr valve could also be the cause If your kicking o2 sensor codes
