OK now check engine light came on and the code I pulled is multiple missfire PO300. Any Ideas

 

P0300?
Dealer service center.


Do some research on this site and you will see why I recommend it. A P0300 is THE worst code to disgnose and fix.

 

P0300 IS RANDOM CYLINDER MISFIRE.

 

How's the fuel? Do you have fairly fresh fuel from a fairly high volume gas station. You could try adding some fuel additives for cleaning the system.

Crank no start when cold. The engine may crank over very fast, as if there is low/no compression. It may also run rough for up to 5 minutes after starting the engine and may exhibit a P0300 DTC too. This may be caused by sticking valves due to fuel contamination. When the engine is cold, the compression on multiple cylinders may be at 0 PSI. The engine also may pop through the intake or exhaust while cranking and the spark plugs may be fuel fouled when inspected.
