  • miata misfire

    My car randomly started misfiring today, drove down to school normal as could be and today i went to go to the store and it was misfiring. I've had a check engine light on from from the catless pipe but i doubt that caused it, and i have no tools at school to work on it, any ideas? Coil packs maybe?

    I'd say go cheapest to more expensive. Check / replace the plugs, then the wires (miatas tend to eat up plug wires for some reason) then the coil packs.

      Did the CEL flash during the misfire event?

      You need to read the code.

          Do you have an Advance Auto Parts or something near you? Most parts places will read the codes for you for free, or let you take a reader out to do it yourself.

                  Wow, you have internet service there? :lol:
                  I've actually been through there when I was helping a friend look at colleges.

                  Unless their website is wrong, Advance has a store in Cochran:

                  175 E Dykes St
                  Cochran, GA 31014
                  (478) 934-8686

                          Go to walmart. Buy a code scanner. $25 for a basic one.

                            The 99's coilpacks are known to randomly funk out and start misfiring. Next time it starts running on 2 cylinders, open your hood and push on the wiring harnesses/connectors that connect to the coilpack. My 99 was doing the same thing and when it did, pushing on those wires would make it instantly go away.

                              while I agree with the coil pack issues, I'm going to disagree with Mike's advice to start pushing on plug wires. there's a reason why they make those long, insulated handle pliers for manipulating plug wires on a running vehicle.
