I have a 1998 dodge intrepid.2.0l , I have done a diagnostic and it says it has a misfire in the #3 cylinder.
The car does run rough and miss's , but there is nothing else wrong that i have found.

mileage is 155,000


nee some answers before i get into some money old this older model card.

thanks

p:s could it be . coil, as plugs and wires have been changed?

 

To make sure you didn't get a bad plug or wire, swap them to another cyl. Next I would look at the injector, you could run a cleaner or have a shop that runs a cleaner under pressure ...I don't think the coil because it SHOULD throw a code.
