runs good, then bad, then shuts down

I'm with HalifaxShops on this one.

Easy way to check.

Buy one of these. really cheap!

Use it when the car is not starting.

You will need a helper to turn the key while you observe the tester.

Insert it between the coil and the coilwire. then check for spark in the tester by trying to start the engine . If ok, then insert between the sparkplug and ignition wire boot. Try starting the engine. If no spark in the tester , you have an ignition problem , not a fuel delivery problem.

This thing has helped me trouble shoot everything from mowers to my Duster. One of them tools I don't use often, but glad to have when I need it.
