Car Forum / Ford / Ford Mustang / April 20051996 cobra stuttering on acceleration
4.6 dohc 32v 57,000miles new plugs,new air filter, new oil filter, new fuel filter obd2 say miss in cylinder 4. OBD2 says everything else in spec. Have not replaced wires but I checked them and they are in spec. Wire 4 reads ~12000ohms. Anybody ever check there wires to see what the resistance is? Don't want to spend $130.00 on wires if they are OK. I may have a bad exhaust valve too don't know yet. I do excellent maintenence on the engine but I do drive it hard. What kind of plugs are you using? Perhaps you or your mech broke #4 when installing them. Is 130 bones the cost from the dealer for wires? You should check for aftermarket wires from MSD or others. Are you sure that isn't 12K milliohms?

Understood and I agree, but in my case I ripped out the wires and reinstalled them and all was hunky dory after that. Dave Same problem w/ me.. was partly due to spark plugs, but mostly due to ignition wires. Mine were $55 for a 98 Mustang GT. I don't think wires are $130 for your car... even factory. -Mike -- Melt away the Cellulite with Cellulean! http://www.MeltAwayCellulite.com/ > 4.6 dohc 32v 57,000miles > new plugs,new air filter, new oil filter, new fuel filter [quoted text clipped - 6 lines] > I may have a bad exhaust valve too don't know yet. > I do excellent maintenence on the engine but I do drive it hard. Had the same problem on the same cylinder, reinstalled the wires and the stutter went away.

It is possible that the one that feeds cyl. #4 is malfunctioning. Possibly a crack allowing moisture in. Is the stutter worse when it is cold and damp outside and the engine is cold?
