I apologize up front if this is the wrong place to post this!
Im having a bit of a running issue with my car. Its a brand new install so the issue is also new, not like it used to be ok, but now its not.
Anyway, I have an MSD 85551 distributor, and 6530 6AL-2 programmable ignition box. Car starts and runs, and seems to idle fine. Get it up to 1900rpm or so and its buzzy and crappy. Not quite a misfire though. When driving, under very light load, like taking off very gently, it then feels like a bit of a misfire. Timing with the light at idle is 12 degrees or so.
When I pull the cap off I see the burn mark is way at the edge of the post, like my timing is way advanced. http://maxboostracing.com/msd.jpg
Im running pretty much default program in the 6al2 now, so its set up for 8cyl, and 6500 rpm redline. Everything else is untouched.
I double checked wiring and grounds.
Do I need to run the distributor locked out?
Really driving me crazy, so I appreciate any tips. Oh, I did post my question on the MSD help forums but I got no responses.
