whats up.
i have a 94 3100 gt
with 170298miles on her.
and she has some balls..lol.

anyway.
when she's first started or after i let her sit for awhile she seems to have a misfire.

rpm's between 1,100-1,300 she shakes bad.

and when i'm on the highway and the rpms under 2,000 with the t/c locked she shakes.

i've checked the coils, replaced the icm.
replaced the pcm NUMEROUS of times.
come to find out i need to have a 94 pcm for the same make model AND trim.
so 94 is a picky year.

i looked at my rapid fire 6 plugs well 2,4,6, and wll of em' have some white stuff on em.
and 4.6 also have some red crap on em'.

oh btw this site's pretty cool.
i had a gtz....

Is it white flakey ash?  If so then you probably have an lower intake manifold leak.

This may not be the missing problem, but it would be an issue.

ehh no.
but it seems at higher rpms she boggs sometimes.
but that seems to happen when i use that chevrontechtron...
