1994 Camry 4cyl auto, 183K miles. The car had run fine since I bought it 1 year ago. One morning it wouldn't start. It turned over just fine, but no fire. Had it towed to dealer. They replaced timing belt, air intake control valve, cleaned the fuel tank?, replaced plugs. The car ran fine for two days, then began to stall once warm, wouldn't idle. I took it back to the dealer, they said it must be the distributor cap, rotor, and plug wires. I just told them to give it back to me, since I can go on a parts hunt just as easily. Anyway I replaced the distributor cap, rotor, plugs, wires, fuel filter, PCV valve. It ran a little better for a few days, but then right back to the stalling when warmed up. It finally died and wouldn't start again. Had it towed back to the dealer. I got the service manager to look at it, and he immediately said "It's the distributor". They replaced the distributor ($473) and all seems good. I'll let you know if it holds up since I've seen others in this space say that the distributor was replaced but wasn't a permanent fix.
