Turbo Miata Lean and AFR’s aren’t reading in tunerstudio
1991 Turbo Miata (SpeedyEFI ecu)
Recently I went for a drive and it all of a sudden started going lean. It goes lean mainly in cruise areas and sometimes at idle. I ended up changing the fuel filter and fuel pump strainer, which didn’t fix it. I then redid the wiring for the Wideband (AEM x-series) and still am not receiving a reading in tunerstudio. I’m positive that all the wiring is correct, is it possible that the o2 sensor itself needs replaced? I’d love to hear some ideas. Thank you for your help!!
