I had it in the shop 8 months ago, they replaced the head gasket, iginition coils, plugs. The code went away $1700.00 later, but it is now back. I run a good oil and have it changed faithly.
The code P0300 is showing on the ram truck, what is causing this? on 2000 Dodge Ram 1500
should be under warranty,so return and have them ck it out.
