[QUOTE="CMOS, post: 437912, member: 15462"] Update 7-2-17: I had some time to fiddle this weekend and what I found doesn't sound good: I replaced the fuel pump and found no difference in the symtoms: starts and runs fine then idle gets low and very rough, then dies. I pulled the plugs right after the symptoms showed. Top is fine, bottom plug is fouled with WATER. I repeated the test after I cleaned both spark plugs, and got the same results: starts and runs fine, then 2-3 minutes later the idle drops and then motor dies. Bottom plug fouled with water. Please help. How the heck can this happen? CMOS [/QUOTE]
