Default 2002 Mustang GT with random misfire

Hey i just came across this thread and im trying to figure this out too cuz its doing the same exact thing on my car. i just got back from sac and its misfiring on a lot of cylinders! thsi has been happening for a few weeks now and since then i changed my plugs to ngk and coils to msd and it still misfiring like hell and sputtering when the engine light flickers! The codes are p1000 p316 p300 p301 p302 p303 p305 and p306! Ive switched out injectors and coils to different cylinders to see if it follows but it doesnt! Where can i look into! What can the problem be, thanks

Jason

You might need to check your fuel pump and/or regulator. Might be starved for gas.

Wow sounds strange I woulda guessed coil packs... i had the same problem... now this might sound silly but are the wires in the right firing sequence??

I agree with Chris, check your wiring job. Also check for continuity in the coil circuit (Haynes manual has procedure).

COULD be a lot of things, including fuel filter, pump, etc, but the list of trouble codes might be a hint - its NOT misfiring on some of the cylinders, leading me to believe its got some wiring issues...

Place to start, at least.

I just had work done on my 04. My stang was misfiring and was acting like it wasn't getting gas. Thought it was fuel pump or filter but it ended up being the ignition coil (#8). Hope this helps.
