ECM code questions?
I just replaced my 4.9 litre 6-cylinder engine with another engine of the same
size in my 1996 f-150 4x4. I had 5 codes show on my code reader, and they are
102, 1401, 1131, 1132, 1151. what are the problems that are causing these 5 codes to show upon my code reader?

P0102 Mass or Volume Air Flow Circuit Low Input
P1401 Differential Pressure Feedback Electronic Sensor circuit High Voltage
P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1
P1132 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 1
P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2
Your having major problems with your emissions/af sensors. Start with checking for a vacuum leak, then by swapping the MAF with a known good.
