83 chev, 350 engine on propane with turbo 400. Coming through the tunnel, engine started to get a bit warmer than normal, didnt think anything of it. About half a km later she started to lose a bit of power and run a bit rougher. Pulled over, shut off and checked everything over. All fliuds seemed ok, couldnt check coolant cause of heat.

Fired engine back up, runs fine in park but once in drive it lugs and lurches, oil pressure drops as engine is being lugged. Any ideas what causes this?

i dont know either, im gonna check'r all over. Just realised maybe the vaccuum line into the tranny popped out, i remember it being a bit loose. I hope it something simple.
