So changed the plugs and coils in a work truck yesterday. That had 3 misfire codes all 2 on bank 1 and 1 on bank 2. While in there replaced upper manifold gasket. Only sensor unplugged were throttle body and evap purge solenoid. It spins over fast enough i smell fuel in the tail pipe. What should I look for next. Or what would you guys look at next. Plugged the scanner in on it. And it shows throttle when it’s applied and spark timing changing. Just beating my head on it. Tia for any help.

 

did you ever figure out the cause of your problem ?
