tue my engine light came on with code p0301 cyl1 misfire, vacuum leak, or high or low fuel pressure. i parked truck til fri and engine light was off, but the truck still stumbles comin out of every gear and smokes a little bit. I've changed #1 & #3 injectors before with reman bosch from alligator replaced 3 6mo later. I don't notice any fuel in the oil, is the injector the best place to start?
