@@DeejayDenz P0172 and P0175 are too rich fuel on banks 1 & 2. Yes and no. There’s lots of possible reasons for these codes to kick off. Some are Faulty oxygen sensor Clogged fuel injectors Fuel pressure regulator issues Vacuum leaks in the intake system Malfunctioning mass airflow sensor You need to look up vids to test your MAF sensor to make sure it’s working correctly before you start a parts cannon and just throwing parts at your car to try and fix the issue. Make sure you don’t have a simple vacuum line disconnected somewhere and it’s dumping fuel into the system. Try the simple fixes first.
Do we need to remove the MAF O Ring before we spray the cleaner on it? And should I reset the ecu using the fuse method or battery method after. My long term fuel trims are negative -5.8% in both banks and afr is lambda 0.82 or 12.2 afr. MAF is reporting 9.8g/s of air at idle and I’m getting 7 mpg even with a light foot.
@@MathuCampbell You don’t need to remove the O ring if you use MAF cleaner. DONT USE ANY OTHER TYPE OF CLEANER or you risk damaging the sensor. You don’t need to reset the ECU if the vehicle was running properly before the cleaning. You will need to idle and drive the car a bit after the cleaning so the computer can recalibrate based on the clean sensor depending on how dirty it was before. I usually see the car running normal again the next day. If you continue to have poor MPG after cleaning the MAF, look for other issues. Sometime a simple vacuum leak can cause havoc with MPG. Look for a loose vacuum line.
Keep up the great content. My isf is out of extended warranty at the end of Feb so it's up to me now...
Thanks and will do! Planning on a 60k service video with trans, plugs and rear diff soon.
Could this be a reason why you would get P0172 and P0175 codes and a VSC check light on dash?

Good vid
Thanks. Hope it helped
@@cpfb68cleaning it right now
Great video bud, I have a Lexus RCF would the process be the same? Do you need to do a relearn on the throttle body once you move it ?
Same process and no relearning needed. Clean, dry and reinstall.
Nice Lexus bud 👍🏾
Thanks! Just trying to keep her running and looking like new!
Nice 👍🏼
Thanks 👍Just tryin to help everyone out.
