Attention: TDR Forum Junkies Will clear itself on the next start generally.
When the CEL is on and the 0602 is present the cylinder combustion is rough and mainly only at idle. As soon as aditional advance is requested the cylinder combustion smooths out to normal.
I had to get fuel at very out of the way location (ie poor fuel quality?). Seemed to happen less as the tank was recirculated through the fuel filters after about 1 1/2 hours (about 6 tank recirculations). Happened on another tank of good fuel though until some fuel was used from "max full", (ie gravity feed) and gravity feed turned off to allow tank fuel volume to start being used.
Does set the companion 1693.
FP is steady 15 psi at all times.
Recent changes.
Added an AUX tank to the bed. Gravity feed the aux tank. Gravity feed on when OEM tank filled and left on. Might have something to do with the 0602?
VP44 return line goes back to the tank filler line.
Possibly air in the VP44 line not able to vent adequately because of fuel in the tank vent line?, causing VP44 to have difficulty expelling air?
At all rpm's above idle cylinder combustion is very smooth and no missed combustion events.
Ideas?
