Engine Mechanical problem
2002 Nissan Frontier 4 cyl Two Wheel Drive Automatic 138000 miles
My Frontier idles ans run well until it hits about 45 then it run rough until it gets to 65 then it smooths out. It sets an error code of P301 - missfire cylinder 1. I have change the plugs, plug wire, distribute cap and rotor. I'm not sure what to try next. I thought maybe the coil but only cylinder 1 is giving be the code. Thanks for you help.
