help! i think i broke it [ignition/rough running]

[Ben Swann]

Alan,

My experience with this phenomenon, and I have seen it many times on the NG/NF setup, is ignition related. Start with check on cap and rotor then go to wires if no fix there.

The humidity part is a dead giveaway - bet the car is running fine today if no rain, but don't wait to fix as it will recure at likely the most inopportune time.

[Ok, I was out last night in my 90q (NG engine) messing around on a rainy
evening, so I thought I'd try some launches. All was good, but on the 3rd
attempt of I went then the car proceeded to buck terribly until it stalled.
It took me a few minutes to get it restarted, but when it did it sounded ok
and revved as per usual. But pulling away entering 1500-2000 it would
proceed to buck real bad, same for second, although 3rd and up seemed less
noticeable. To drive through these areas when pulling away I actually have
to slip the clutch.
Any thoughts on this? I have thought through as best I can and can only
think of a mechanical problem relating to the engine.  What is the likely
hood of a t belt skip in these conditions? And would it manifest itself in
this form?
Many thanks.
