The 4 Runner is back from the shop and is running great! The #3 fuel injector was bad and had actually come apart (the mechanic said it came out in two pieces). The other 5 injectors were all tested and cleaned and they were fine. The issue with #3 was causing all of the remaining fault...

Latest update. I did some digging on the forum and found how to test the fuel injector coils with an ohm meter. I was able to easily test the injectors for cylinders 1, 3, and 5 (since they are not under the plenum). Here are the results: Cylinder 5 = 14.7 ohms Cylinder 3 = 31.4 ohms...
