What octane fuel are you running? My 3.0L diesels like crazy unless I feed it 91-92 octane.

post your engine serial number. One of the iboaters can verify the correct plugs.

ive heard that as well. I guess i dont want to commit to the higher price gas every trip. Ill have to try it though, nothing else seems to work.

ill check the pcv. that should be a cheap fix. How can i look up the correct plug? i replaced them last year, but just matched what was in it.

No PCV valve on these engines. That hose from the rocker cover is just a vent for the crankcase, it's not a PCV valve.

Correct spark plugs are NGK-BPR6EFS or AC-MR43LTS (same plugs as the Vortec V6 and V8 engines).. Please don't use champion plugs, they are dreadful in mutli-cylinder engines, especially marine ones....

You might want to read what happened to another member when his engine dieseled on shutdown...

Hmm. 25 gallons * .10 = $2.50 Doesn't seem like much of a commitment
