2008 Scion XD Idle Issue
I am working on my wife's cousin's vehicle. 2008 Scion XD, 1.8. 152k miles.
I replaced all 4 spark plugs and ignition coils and cleared some misfiring codes. I am currently in the process of replacing the upstream O2 Sensor due to code P2237 which is a PITA to access.
As of now, when I'm gear, drive or reverse only, the engine bogs down to less than 500 rpm and feels like stalling out but doesn't.
Any help or suggestions would be appreciated, thank you
If the fluid and filter haven't been changed in 152,000 miles, a fluid and filter change might not do any good at this point.
