Have you checked or replaced your spark plugs?
What about your o2 sensor?
What about your injectors?

OBD-II Trouble Code: P0300 Random/Multiple Cylinder Misfire Detected

yep and it is pumping fuel in to the cyclered but its not running so i dont think it a injector

 

[matt5112]

Did you gap the plugs?

 

[zach101]

yep

Unplug the MAF sensor and give it a try.

OR.

If it is just cranking...you prolly need to have the ICM tested...because that'd be the next thing. It's what the coil packs sit on.

 

[zach101]

we tested that. im going just put it in the shop
