Engine Performance problem
1998 Honda Civic 4 cyl Front Wheel Drive Manual 140000 miles
Hi I have a 1998 Honda civic dx that has been driving me nuts. When I start the car it will run really rough for about 30 seconds, the idle will almost drop off and pick back up. When I apply the gas it hesitates and will clear up after a few seconds. Also when I first take off engine cold the car will fall on its face, so I have to feather the throttle and soon after the car runs fine.
The check engine light is on and has a code of P301, says misfire in bank 1.
I replaced the spark plugs, wires, cap, rotor and fuel filter, this did not help. Also I checked the fuel injectors with a multimeter ohms reading and they all check out equal. Please help.
