I replaced my MAF Sensor and I have a P0102 code with "Mass or volume air flow circuit low input". I have replaced the EGR valve, the Throttle Position Sensor, and the Air Filter. After I replaced the Maf Sensor, my transmission has a rough Upshift. I cannot find any Vacuum hoses loose or disconnected. I need some help t6o correct my P0102 code and transmission upshift.

Your new MAF may be faulty or the connection may be bad. A bad MAF will cause P0102 and your transmission to shift bad. Fix the P0102 issue and the tranny will also correct itself.

Quick test is to unplug the MAF to see if the car runs better. Computer will default to other oprtions to make car run. Recheck vacuum for leak by spraying Starter Fluid around all air joints. If Idle increases for a moment then you have a vacuum leak in the area.
