Hi Fellas,
May need help with this.....I generally cruise at 4200 RPM's
Coming home Fri afternoon, throttled up to 4200 and it sits there for 5-10 seconds then comes back to 36-3700 where she'll sit for 2-3 seconds...then comes back up to 4200 where it stays for 5-10 seconds....then back down to 36-3700 where she sits again for 2-3 seconds, then back up to 4200.....this process goes on and on and on...same symptons.....I should note, this only happens above 3000 rpm's and the "drop" is always the same (600+- rpms). It sounds good, no cough/sputter etc, no smoke...it's a smooth increase/decrease, almost as if someone is throttling up and down...it's also not a sharp or sudden increase/decrease. Saturday the wind blew so I checked and swapped out the plugs and water seperator filter though all looked clean...Sunday I fished again and had the same problem. I spoke to my mechanic who will HOPEFULLY get a chance to look at it Tuesday or Wednesday. I mentioned to him the possibility of it being the VST screen or a fuel pump issue and he said (again without looking at it yet) that it sounded to him like a coil problem or possibly a spark plug wire(s) being bad and that's where he'll look first. He said if it was a fuel starvation issue it probably would not be recovering so quickly. Any opinions? Also I should mention, I do not have a fuel flow monitor, but it seemed to me Sunday's trip gave me HORRIBLE fuel burn numbers. I think I burned a TON more fuel than I normally would have on the trip I took.
