[86GT]

check ya timing

 

[86GT]

Timing too low or not advancing.

yea, check your timing rel good. Something dont sound right there!

As much as I would like to think that its just a timing issue.... Sounds like there might be a bent valve, very loose rocker or a broken valve spring. Best thing to do is a leakdown test to make sure that is not something worse!

+1. Sounds like a valvetrain problem.

 

[86GT]

the thing is that this only happened after we swapped out the distributor

This may sound like a dumb question but did you check the firing order?

Unfortunately, I'm with the person who suggested it might be a valve.
