my corolla had sit awhile before i got it i replaced front brakes, fuel filter, spark plugs, air filter, plug wires and distributor cap, and throttle positioning sensor. I was driving it home after work when it started to stutter and then quit. So i got another distributor because i thought the igniter was bad. I also cleaned out the cat because it was almost plugged. It started but was barely running. I adjusted the timing by moving the distributor the whole way to one side and it ran better but if i would give it throttle it would die. I adjusted the throttle positioning sensor the whole way in and it was better. I drove it for 25 minutes to school but before i got there it started to stutter then died and now won't even try to start. Any help would be greatly appreciated.
