@annikacarter_: I had a feeling it had to be something simple and electrical!! One of y'all mentioned MAF to me last night and the lightbulb went off. Does @haltechecu have very clear instructions on their website with wiring for all the OEM sensors (MAF included) and how to wire them with the ECU (including how to delete the MAF)? Yes. Did I read it? Yes. Did I remember to do it? NOPE! 😂 #oops #mazda #miata #builtengine #jdm #DIY #garage #cargirl #mechanic
