I just purchased a 1996 Ford Bronco. The check engine light is on and I have run the codes one is saying that it is running to lean and I dont know what is causing that the next code said that it is misfiring on the #5 cylinder. I have replaced the spark plugs, wires, and distributor cap. I can't think of what else that would make it misfire on one cylinder. Please help

Try this check the DPFE/EGR

A misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

A Random Misfire code P0300 usually indicates a vacuum leak or bad fuel
