What about plug wires? how many miles on the vehicle? what engine, SPI 2.0 or DOHC 2.0? I personally never seen a problem with focus fuel injectors.

Re: Running on 2 cylnders HELP

ok 2001 ford focus. 2.0 Split Port 159000 miles Fuel pump is good. Fuel filter changed. O2 sensor changed. New plug wires. I am beginning to think that maybe it has something to do with the crankshaft sensor, or the camshaft sensor. If not... I am ready to drive I mean push it off a short peir.

Re: Running on 2 cylnders HELP

With that many miles I would suspect the timming belt has slipped a couple of teeth causing your engine to be off time. You need to remove the front engine mounting bracket and timming belt cover and have someone crank the engine over be sure to unplug the coil pack. Then you can see if the belt is missing teeth. hope this helps.
