I’ve got a 1994 st204 celica with a 5sfe motor, it runs perfectly for 15-20 until it warms up then it starts misfiring and stops. Then when the engine cools down it will start and run perfectly until it warms up again. I have replaced the igniter, internal distributor coil, distributor cap, rotor button, spark plugs, spark plug leads.
Any suggestions would be greatly appreciated!
