LostCube...
Did you ever figure this out?? I have a 2001 Rodeo with a very similar issue (except mine is P0301)
To date, I've done the plugs and wires. Dont remember which kind of plugs I bought, just know they were recommended by Oreilly after a quick lookup on their system.
I've also done the camshaft position sensor. The fuel sending unit. Valve cover gasket. Air filter. Fuel filter. And in unrelated news: the alternator and battery.
I just ordered a new coil pack (mine's the 4cyl) ... and that pretty much tapped my account. I hope to get it on Friday and install same day.
Sometimes... before my truck warms up ... there's a puttering noise when I accelerate. Regardless... P0301 never wants to go away.
How did you situation end up??
