Fuel Injector
 

Will a bad fuel injector cause a car to have a miss, I have a 87 5.0 basically it a street car everyday back and forth to work kinda car, but will clown if need to, what I'm asking if an injector would cause a miss when replacing those injector which injector will be the best for the money. In search of the miss I've changed wires, plugs, rotor, checked vacuum hoses, someone says its running rich in the fuel try replacing injectors so thats where I'm at.

How many rounds are on the engine? It's very possible. With a factory intake it'll be hard to pull the driver side injector connectors one at a time to test if it is. If you pull the injector connector while it's running and the miss stays the same, it's that injector, but they should really be replaced all at once. If you're stock, use 19lb/hrs....

I have a 95 mustang what would cause the exhaust be so rich i cant seem to get the right levels

Welcome to the forum, but you should start a new thread when you have a question or looking for advice. And be as detailed as possible when explaining your problem, and some details about your car. That way we can give you accurate advice.

Also, explain in the new thread why you think it's running rich and how your checking those levels.

how do you know it's rich?? your nose??..lol if that's the case that's not a good method to verify.
