 Subject: Misfire along with P1391 code
IP: Logged
Message:
2001 quad cab 2WD 3.9L with 132,000 miles. Random
misfires cyl 1, 2 and 5. Runs rough when cold, runs better
once warmed up but again rough when cold. Just got this truck
and don't have money to sink into it. Have heard it could be as
simple as 02 sensors to a blown head gasket!. Any help would
be greatly appreciated.

Message:
My code reader links this code to the camshaft position and suggests:
-check the camshaft position sensor (the sensor is in the distributor assembly)
-timing chain loose or possibly slipped
I replaced the camshaft sensor, the distributor cap, the rotor and the wires and the code stayed off and the truck runs much better but I don't know which one of those items actually triggered the code to begin with. Probably the camshaft position sensor but I didn't bother to test the old one that I replaced.
