I agree with the fuel filter analysis. The fuel injection is
programed to emulate the accelerator pump and the choke functions
of a carburettor. Thiat it it gives an extra squirt of fuel when
you accelerate, or it is cold. If the fuel filter is clogged the
fuel injection can't give the extra squirt and you get stumbling.
The same thing happened on my fuel injected motorcycle. It
stumbled and coughed when it was cold, then ran fine when warm. It
would also stumble when I accelerated. I changed the fuel filter
and Bingo, no more problem. The stumble was so pronounced it felt
like an ignition problem.
Drive Safe,
Joe
