MAF, O2 sensor, Reverse lockout issues solved.
1 - It become very hard to put my car in reverse. Replaced the Reverse lockout sensor. No change.
2 - Car threw P0102 MAF code. Replaced MAF. Same code remained no change.
3 - Replaced both of my O2 sensors. Same codes no change.
4 - Found the issue. Engine SENS fuse was blown.... $5.00 for 2 fuses later fixed....
Really really annoyed and sad at wasting $200 on a bad fuse.
