New to this forum,so hopefully i get it right.i have a 96 mustang gt with 119,000 miles,the car ran great.today i changed the oil and filter,and changed the original spark plugs,now it sputters real bad,any advise please.

 

might want to check your o2 sensor connectors , did you check the gap on the plugs?

 

havent checked o2 connectors will do,i was wondering if there could be bad injector or dirty maf sensor?

 

and yes gap is at .053

 

How did you replace the plugs? One at a time or did you remove all the wires first? Maybe a wire is crossed.

Also, how old are the wires? It's possible when you took the wire off the plug, one or more connections was broken/loosened. Or, the wire is not fully seated on one or more plugs. With good wires you should be able to hear an audible metallic 'click' as the connector in the wire makes a solid connection to the plug. If one or more of your wires didn't make that sound, pull each one off the plug, inspect the wire and connector and try again. You might need to take some pliers and gently squeeze the wire connector down a bit to get a better connection.

 

Yeah,that worked,changed the wires and problem is gone,thanks for the suggestions

 

cool, glad you got it fixed!
