I am driving from BC to Ontario in a 240z with 10,000miles on a rebuilt L28 triple webers. 280zx distributor. Fuel pressure is 3.5 psi. It ran fine for 12 hours to Calgary, in heavy rain, and for most of the way accross the prarries. Currently in Thunder Bay.

Fixed many problems related to this in Calgary with zKars, as well as many other unrelated issues along the way.

She still luggs when trying to give power to the wheels, especially under low RPM. Checked spark plug wires again, 3 and 4 are intermittent. Switched all wires (plugs are 2 days old, new distributor with old cap)

Gives spark perfectly when holding the plug wire about 1/4 to 1/8 inch away from the female connector on the dist. cap; gives little/intermittent spark when pushed into position.

Cleaned dist. cap, cleaned terminal ends, cleaned plugs, cleaned roater, same problem.

Everything is new except for the cap! Looks clean! I'll replace the cap (anyone in Thunder Bay have one?), but what else could this be? Fuel filter just cleaned. 91 octane used with the occasional octane booster (likes 92).

No backfires, except on occasional downshift decel.

Any ideas appreciated, orginal thread is below:

Hey,

Sorry to hear about your car troubles. I can tell you that if you're continuing East that you SHOULD get it looked at before you continue because theres not much from there to Sault Ste Marie, about 9-10 hours away. If you get stuck you're on your own or will have to get towed to the nearest little town that likely won't have a garage/mechanic. If you do get stuck and have a cellphone *OPP is the police number.

Good luck on your drive!

Thank's Zak; I won't leave without fixing this.

A Question:

No parts store wants to open a bunch of random dist. cap boxes to find those that look the same as a 280zx, though it seems like this may be a more genaric part to me -- Does anyone know offhand which dist. cap's may fit a 280zx distriburor?
