    I have an 04 2wd edge with 310k. I have been chasing down a P0300 code for over a week now with no luck. Engine started running rough and lost power. I sprayed 2 cans of starting fluid under the hood and no leak found. shows random misfire on 4,5, and 6. I replaced the plugs, wires and coil. still the code and not running well. cleaned the MAF, replaced the cam sensor. replaced all 6 injectors and the fuel pump and filter. was starting but dies when I touch the gas pedal. Last night I replaced the fuel relay, now wont start at all Throwing a 0174 code now. Any out of the box suggestions? or in the box suggestions? At this point I cant even get it to a mechanic.
