Help! I just bought a 1994 Mazda 929. At first it would start to lose power while driving down the road and then completely die. You could wait a little while it would start back up and do the same thing then graduated to not starting at all. The Mechanic I took it to, now has it where it will start and idle for as long as you want but the minute you hit the gas it dies. He is at a stand still, we do not have an owners manual for the car.. Any ideas??
