Hi i have a 2.5L ranger that i cant get to run right. If i just let it sit after i start it it will run fine but if i give it any gas it starts to run like crap and stall. After its warm up it runs ok. I was told that the code was a p0302. That a miss fire in cylinder 2. I tried a number of things. New wires, spark plugs ,new coil pack ,fuel filter and idol control valve. I just cant figure the damn thing out does anyone have any ideas that might help. THANKS JOE
