Did you replace the fuel filter ? and check the air filter.

take out the o2 sensor on the drivers side exhaust manifold and drive the thing. not for long, as that hot exhaust could start burning stuff. It won't hurt anything. If it runs better, you have a clogged cat. you will know when you start it, but still drive it up n down the block at least....

My 1993 f150 xlt 4x4 acted the same. As if it was out of time. I replaced the distributor and It fixed that problem. But now it just has no acceleration. Have changed every sensor and filter I can find and still no power. It kicks in the passing gear just to go up a small hill. Any suggestions??
