my car keeps on shutting down while i drive it, normally when i slow down or come to stop. the battery and accessory lights turn on, and i have to start the car while moving to keep the car going. just happened after i ran a new car audio amplifier (but power not connect in yet. just ground), and also disconnect the ecu. not the battery (brought it to pepboys for a battery test. said it was fine). not alternator..disconnected from battery while car was running, and car did not stall. also ran above 14v with multimeter. so i'm thinking its the dizzy since it happened to me before..is there a way to test the dizzy? can it be something else?

 

someone should confirm this, but this is what i found online:

1) pull the wire from the coil to the distributer and lay the end of the wire about a half inch from the metal of the engine. Crank the engine. You should see a hot blue color spark jump at least a half inch with a snap. That proves the coil and wire to distributer is ok.
2) Wires usually measure about 7K ohms each. If they measure 20K, there is a problem.
3) Reinsert the wire from coil into distributor and pull spark wires one by one and repeat the initial test. Lay each wire one by one a half inch from engine block and crank engine. Observe that spark is hot, blue color and with snap. If all wires show weak spark you have bad distributor cap or rotor, or bad wires.

 

can anyone else chime in what else the problem might be..
