I have a 93 supra n/a all stock with automatic tranny and having problems with it. First the engine light and warning light turns on. I check the batteries and alternator and still good. Drove fine for a week then starts to idle very low. Low enough to kill the engine. It also seems like the power is not there anymore. And now the car is not starting. The engine still crank but won't start. If it start it then idle for little bit and lower the idles then dies out. I'm wondering if its the spark plugs or the distributor. I replace a distributor rotor and new distributor but still won't start. Can anyone help me out with this.
