One more before I call it quits for the night. A 2011 BMW 328i with a starter that spins but won't engage. I gotta see this. Remove the plenum to access and remove starter. Test the starter with a jump pack. Sure enough the gear spins but doesn't slide out on the shaft. Disassemble starter and the gear is froze (rusted) on the shaft. An internet search shows this to be a common BMW problem. It seems that the Ultimate Driving Machine is really just the Ultimate Parked Machine.

It worked !!! Had a 2013 Cadillac SRX with a broken touch screen or Cue screen as some call it. The whole assembly is quite pricey so I gambled on buying just the screen from Amazon for about a hundred bucks. After removing the control assembly, remove the trim pieces and the storage compartment from it. Then it's just 6 or 7 screws to hold the screen on and one ribbon cable to unplug.

Had one that threw me a bit this week. A 2012 Toyota Venza that would act like it was in reduced power mode. When I first looked at the Accelerator data i could see that the throttle angle was not matching up too well with the input from the accelerator pedal. A closer look and I could see that the Air Fuel sensor was showing a pegged lean condition under acceleration. The only code I was getting was a misfire on cylinder one. After verifying that all was well mechanically and spark wise on the cylinder I started going after a fuel problem. First to check the pressure, good at about 50 psi and steady under load. I happened to drain off some fuel in a container and got the first clue, cloudy looking gas. Let some settle in the cup and it was about 10% water. Drain the tank and run some good gas through the lines and we have full power again. Now the throttle angle more closely matches the input from the pedal. The only thing that I can think is that the ECM sees the lean condition and starts to limit throttle angle. It almost felt like driving a vehicle with a plugged cat. It never misses or stumbles or surges, it just won't go.

Good work Bob.
Back to basics & fundamentals again.
The fuel quality has always been an issue, even since the days of Carburetors & points & mechanical fuel pumps.
Many years ago, it was so funny, the mechanical fuel pump had frozen overnight and instead of looking at the mechanical fuel pump, what was seen was a basketball size glob of ICE encasing the pump.
Testing the fuel pressure physically, then taking a sample (since you're already there-!!), then using your HUMAN SENSES and SEEING the condition of the fuel, and not relying entirely on the electronic digital data presented.... kinda makes things simple, doesn't it?
The more things change, the more they stay the same.
Same thing with your post about the starter drive rusted. Fundamental once you get there.
I just expect good work from you-!!

If you are interested, the WEBER AUTO youtube channel has been running a series of videos dissecting and explaining the drivetrain and electrical components of a 2017 Chevy BOLT. The videos are informative and professionally done as well as very detailed. Weber Auto is Weber State University. https://www.youtube.com/channel/UCtr...sUwVJjL8Kw_q5A
