Hi, runing rough can be caused by several things, you can start by checking the simple ones first, fuel filter, air filter, spark plugs, add a good injector cleaner and leave the car runing for some twenty or thirty minutes ,if it dosnt change,you may get the injectors cleaned by a pro shop.....good luck....

Whats wrong with my 1984 ford bronco running rough?


It sounds like there could be a miss. A miss is when the timing of one or more cylinders is off, causing it to run rough and sometimes shake badly. Im not positive it's a miss, but if the distributor or distributor cap is bad, it could cause it to start weird and run rough. It could also be the spark plugs and/or spark plug wires. There could also be carbon build up in the carburetor. I hope this helps. Sorry it's so vague, but without actually being there, its hard to say for sure.

Smell the coolant. Is there any hint of gas smell? Also look at oil, any coffee coloring indicates problems.

Miss firing


could be a wire crossed, or it's out of time. since you used motorcraft plugs, did you set them properly to the correct gap? replacing plugs without gapping them can cause the sluggishness, out of time can cause the mis-fires and rough running.
