Wanted to get some thoughts on where else to look. I’m running a 3l with MSDS headers, high-flow cat and 24# injectors. It’s fully tuned.
I’ve replaced the O2 sensors and installed MIL’s and each time it came back after a short period of driving. I haven’t changed the coolant sensor at the back yet just because I wanted to hit the accessible stuff first. The car does feel like it stumbles slightly while cruising, but I’m also dealing with a failing SPEC stage 2 clutch and unsure if it‘s that.
I presumed during the tuning process it would’ve gone away as it ran better, and when I asked the tuner said it’s not something he’d touch. And when I got my final tune back he said everything looks good. I’ve recalibrated my wideband just to see if that’s reading odd, but so far it seems within margins. The fact I’m still getting it with MILs surprises me.
