Hello all, to quickly summarize my issue.. I had blown the head gasket, heads went to machine shop put it all back together with new spark plugs start it up did not idling right had a little miss drove good just idled bad. Check engine comes on giving code PO303 so changed the ignition wires. Ran really good next day check engine on yet AGAIN now 2 codes PO341 and PO300. It is driving me crazy someone please help!

P0341 is a camshaft position sensor. Most likely it was bumped in the replacement of the head. Check the wiring to the sensor and ensure it's connected.

P0300 Random multiple misfire. Do you know what plugs were put in the car?

could timing be off? thatd cause the crank code and misfires

 

[jessiinicole]

The wires were from Auto Zone.. Duralast i believe? Why are they no good? What would you recommend?

they meant, check the wires going to the sensor, not the spark plug wires.

The question was what spark plugs were used? Brand and Part number, need to ensure they are correct heat range plugs.

Supercharged, that makes good sense to check the plugs and their gap
