Roadmaster w/ LT1 having ignition issues
Roadmaster w/ LT1 having ignition issues Hi all,
My friend has a 1995 Buick Roadmaster with an LT1. On Saturday the car stalled out and wouldn't start until the engine cooled down a little, but then still ran fine. Prior to it stalling there were no performance issues, etc.
Based on the symptoms (and the fact that a day later the car ran great until it came up to temperature and held for a few minutes at which point it stalled out and could not be restarted) we are assuming it is a problem with the Opti-spark. The shop that he took it too (the one that replaced the opti. 4 months ago) said it is a problem with the ignition module (or some other external module) and that the "Cap and rotor" are fine and that they replaced the "cap and rotor" last time, not this module.
We think they're full of **** and should replace the opti. on their dime.
What do you think?
Thanks for any/all help in advance!

If it seems to help, but does not fix the problem entirely, then get a new ICM, but keep it spaced off the head and you should be problem free.
