Re: Rough at idle!
Seafoam treatment!!!!!!! It will probably fix it but if it doesn't, it will at least help to eliminate most distracting second guessing.
Enter the Seafoam into any vacuum line or directly up the PCV valve. Put second full can into the gas tank.
Any questions; directions are on the can and YouTube has a thousand videos explaining how to do it. Trust me, it does wonders to our engines!!
