Sure, I will look into the IAT wiring today. The flash should be for the manual transmission car.

Another thing I noticed today was that the timing advance shown by torque app ranged between -2 deg to 76 deg. Does that sound right?

6th gear at low rpm caused quite a bit of rattling sound. At RPM over 3-4k there wasn't any ratting sound.

Whoa... That seems really high for timing advance, mine peaks at about +40 I think.

I checked the timing advance again- it varies from 15 to 43 deg.

My MAF wiring is good so I replaced the MAF and the p0113 code is gone. Now I have a random misfire code and the car is still lean on one side and rich on the other.

I plan to change the passenger side fuel pressure regulator / damper next.

Did you re-do the compression test?

Next option would be a leak down test to verify the low compression and see where the compression is leaking out.

This turned out to be an electrical issue. We hired a specialist to look at the wiring and he seems to have figured it out. I really appreciate all your help in diagnosing the issue. The car now runs excellent!
