How am I supposed to check for low vacuum? Reading from the MAP?
Like I said, engine is running fine. Removing the O2 sensor is only going to make it run in open loop and I won’t see any movement from stft

Could you update with your fix?

Any update? Problem fixed with o2 sensor?

my son just bought the car, so I would probably say never… I was planning to do it this winter when I will have some garage time. I’ll try to clean the injectors at the same time.
Like I mentioned before, engine is running fine. STFT is more erratic when accelerating a bit, but when I go full throttle, it looks ok.

Also, which parameter the ecu is looking for in order to throw a P219A? Cannot find that info anywhere. To get a P0171 the ecu is looking for a 25% LTFT. Maybe it’s looking at STFT?
