yeah was probably the system freaking out that something had changed. all good now it seems. car runs extremely quiet now and just shakes a little but no "engine freakouts" as i call em now. i do think the guys at the shop messed up by transmission just a tiny bit but i can still shift into all gearsI got rid of all the Lean-burn system and went old school--i installed a '70 BBD carter, and a new point-type distributor. When I messed up the front end, I had accumilated over 352,000 on the car.
