While it doesn't always work, you can try revving the engine to 7000 rpms. Hold it there for 15 minutes, shut if off, and restart. |

Re: Engine clattering?
I appreciate the help. I am about empty on the gas and I am going to put high octane and hope that is it. I didnt hear it today hardly so maybe it was bad gas. No NEOCON I am from NC. Thanks again....
