The MAP sensor should not be able to affect the inside of the distributor. It sounds like you may have some kind of bad contact in your ignition system? Double- and triple-check the plugs and wires, cap and rotor.
If the stuff you saw in the cap was reddish-colored, I would tell you to get a new distributor. The "red dust of death" is a known failure mode for those...

Well guess what i found lots of under my leak cover ? Yup !
Reddish dust.
I have a brand spanking new distributor, complete with cap and rotor ready to install.
I paid $115.00 - much cheaper than a rebuilt unit from autozone .
BTW, I had just had the coil, rotor and cap replaced around 600 miles ago due to the weak spark issue.
It makes me wonder if the guys at the shop were just throwing parts at it.
( I'm glad i'm doing the work myself this time. )
