my car rev to 3500rpm then chokes... Sometime it'll start but when it starts it'll idle to 1000 rpm and drop to 0-400 rpm back and forth...could it be my throttle sensor or distributor? Because my distributor cap is burn so i replace it already but haven't replace my distributor rotor. or can it be my timing is off. now the car won't even start no more. one more problem, my ecu don't blink or lighted up at all?????????????? any information???????please help........thanks
