for monitoring the engines operation (don't tell me theyre terrible
and shouldn't be used for tuning. I know. Its merely a diagnostic tool)
AFRs are normal until engine gets fully warm after driving and then
runs a steady 25.5 (max of the monitor) on accel, decel, idle, etc.
until the engine cools down.

6. are you checking fuel pressure just at idle? it should increase with engine load.
8. how long have the old set of plugs been in for? have you removed the new set to see how they look after some miles on em?
10. you can't accurately tell afr from a narrowband. do i need to repeat that?
is the car running rough, shitty, poor mpg, stalling, hesitating, etc, or are you only saying its running lean due to the tips of the plugs and the reading of your narrowband?
