2004 Nissan P0301 code
2004 Nissan Frontier 4 cyl auto. I get a P0301 code (#1 cyl misfire). This truck doesn't have a coil for each spark plug , so I was wondering if this code is truly for # 1 cyl , or just that it is the first one checked ?
I changed the plugs, wires, distributor cap ,rotor, fuel filter. Used Sea Foam and Lucas in fuel to clean injectors. Nothing helped. When the truck is in overdrive and low rpm's , it shakes badly. I am assuming this is because of low torque. When it gets to 60mph or I take it out of overdrive the shake goes away.
Listened to injectors and they sound like they are clicking open and closed.
My fuel mileage has suffered greatly and I am at a loss to figure this one out.
