Sputter/hesitation diagnosis

Post by **Mikie** » Mon May 10, 2004 7:54 am

Hey if anyone has any thought I would appriciate it- I was driving on the Freeway and I started sputtering. It would do it more when I would give it more gas. When I changed gears it would stop until I accelerated. It was idling rough, like it was missing and the whole car was like shaking ( but that stoped when I changed the plugs. -Any thoughts? timing? bad fuel pump, bad injector(s)? anyone know how to test the pump or injectors.

-CA18DET (all stock everything)

Timing

that would be way sweet (and inexpensive)but why would it start doing it out of the blue (granted it was fully advanced)...anyway thanks! I'll play with it tonight.

What did your plugs look like when you changed them? You didn't really say that this happened out of nowhere.

I thought they looked ok for as many miles as I have put on them. The tips were no longer shiny, but the ends of the threads were blackened... does this suggest some other potential problem?
