Neil, that was my first thought actually. Alan has replaced the fuel filter
and when he did so he said some rusty looking fuel came out of it...
However, the fuel pressure at the testing nipple checks out. clean gas is
squirting out of all injectors in a nice conical pattern.

Regarding the o2 sensor, it currently doesn't have one installed. However,
it was at one time running fine without it installed... Alan is going to
weld in a bung and put a new one in this weekend to eliminate that
possibility.

Dennis: sorry, but what does it mean to 'cycle the ignition on the fly'?
Also you make an interesting comment about the throttle switch. Could a bad
throttle switch be the culprit here? never thought a bad switch would case
this bad of issues, but what do I know.

John, We have already swapped the coil (as well as all ignition components)
and the ECU with known working ones. No dice.

One other piece of information: as its dying cylinder 1 will misfire if
throttle is applied. It seems to only and always be cylinder 1. It also
seems to be running rich.
