so i was cleaning my TB today and decided to pull off the plug to the coil.. when i pulled it off it had white flaky stuff that almost looks like what builds up around the battery. i figured that this might be a big part of the problem as to why that my car was missing at idle and between 1500-2000 rpms. so i went to pep boys to get a new msd coil later to find out when i got home it was a bad coil so now i have to wait till tomorrow to get a new one in the morning.. do you guys think this could have been causing issues?

Definitely. It's called corrosion.

im real interested to see if this was the issue not the distributor like i was thinking.. but i dont think this could cause problems like that
