I got a text late last night stating the light is on. However, today, the light was off.
Lucky for them, I'll be in the area later tonight. I'll have my OBD2 scan tool with me; hope the code is stored.
I asked the usual questions:
- when did you notice the light
- what were you doing when the light turned on
- where were you when the light turned on
- how long since it was last gassed up
- where did you get the gas
Anything else I should ask about?
I havent changed the plugs yet at 120k. I'm hoping either bad gas or just plugs needing replacement.
Could it be the ECU re-learning regular 87 octane gas as compared to the mid-grade (89?) that I usually fill her with?
