Twisted Tune v0.04 cold start Not quite back to normal. Rpm is still surging. I waited until rpm stabilizes, stopped logging and drove out. While reversing, engine just died. No code. It started right back up. Normal driving is fine but idle rpm fluctuates in park . |

Twisted Tune v0.04 after re-tightening bolts Re-tightened everything and replaced maf sensor o-ring. Bolts were looser than I thought.
Cold start rpm managed to stabilize after 30 seconds. Car runs so much better but hesitation (throttle closure) in the upper rpm range is still there.
Service Engine Soon light is on and got these DME codes:
2BC0 - Mixture control: Fuel-air mixture too lean.
2D00 - Oxygen sensor before catalytic converter, signal lines:Short circuit to earth.
2BDE: Fuel high pressure on enabling of injection: pressure too low.
2C42: Mixture control: multiple fault
2D2F: Oxygen sensor before catalytic converter: Multiple fault.
