My longtime Mountain Biking buddy, Dr. Gonzo is having a bit of a problem. [img]images/graemlins/frown.gif[/img]

Here's his text:
"When going up a hill, or accelerating hard, there is a miss.
At idle, or on a flat road, runs like a kitten.
Started just after I replaced the plugs, wires, cap & rotor, fuel filter, air filter, oil and oil filter.
What did I screw up?"
Thanks much folks!
