  • Who's got a code reader?

    Anyone got a code reader for an NB Miata? I got a pesky check engine light and fuel smell in the cabin. Wondering if it's emissions related or failing coil time.

    I have one of those cheap obd2 dongles to use with the torque app if that helps. Reads codes on the VW pretty good (insert VW jokes here)

      The local auto parts stores (that you say you swore complete hatred for) read these for free.

        They are dead to me! They'd probably read the code and tell me I need new blinker fluid or muffler bearings.

          It doesn't matter what they tell you as long as you get the code. That's what teh googlez are for

            I have one of those cheap OBDII Bluetooth readers as well. I think it worked on the NB I had.

              I've got a handheld code reader and one of the dongles as well. Sub-$20 dongle and the OBD Fusion app works just as well as the actual reader. It can also pull some live data about the car and display it as gauges. So that's pretty handy.

                  Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car.
                  Horsepower is how fast you hit the wall and torque is how far you take the wall with you.

                    Well, Delanie hooked me up, literally. I have the usual Miata codes. Bad cat, rear o2 sensor and EGR. The EGR was cleaned and a replacement Catalytic converter and o2 sensors are on the way. Hopefully this will do the trick. I'm trying to drive a clean car for daily duty. Trying.

                      Was it the infamous EGR code that apparently all 99s throw at some point? I never did completely exorcise that demon. Rerouting a particular vacuum line helped but nothing kept it away for good. The good news was that it didn't seem to affect the car at all other than an annoying light in the instrument cluster.

                        I read that bit about rerouting a vacuum line on miata.net. I don't understand that. My EGR is electronic. No vacuum lines attached.

                        My green 2000 had the same issue. EGR, O2 sensors, cat and failing coils. I have a set of Toyota coils to plug in but I'd need to add an aftermarket ECU to adjust the dwell. I'm not there on this car. I just want a nice clean daily.

                            It couldn't hurt. I mean, we have a website, we ought to at least use it once in a while.
