Guys I have a 94 formula its LT1 and about 6 months ago had to put a new crank in it, put the new bearings and everything in. Got everythign in and car started back ran hot and wouldn't sit at idle. Had to hold the gas to keep it running. Drove the car about 50 feet and it quit. Haven't even been able to get the car to fire up since. Any suggestions? I know i'm not giving much to go by but any response would be greatly appreciated
