The error code p0301 ,This code is related to misfire.The cylinder is misfiring. p0301 this is the indication of cylinder number 1 ,that is misfiring.If the code comes up as p0300 this is the indication of random misfire from all the cylinders.But in your case its indicating p0301 this is indication of cylinder 1 misfire.Check cylinder 1 and replace the faulty cylinder 1 to clear the fault.The spark plugs and the wires connecting to spark plugs also needs to be checked. Keep updated with any more query.Thanks.

Code po301 then two weeks later po133 came up on my actron car runs rough and stals out i changed o2 sensor on back of motor a month ago, plugs and wires.

Change both front sensors-- if you have dual exhaust

What about the PO301 ?
That is a misfire on cylinder #1

Your old O2 Sensor, that was slow to respond,
as well as a misfire, shouldn't cause a stall

You had 3 problems

Engine miss firing installed new plugs still miss fires

You may get one bad spark plug in 50 years of driving

Does that answer your question?

You did not diagnose your problem, which
was a misfire.

Do you have codes PO301 thru PO306?

Ignition Coils cause misfires

Have to know the system your working on
