1996 Camry 4cyl P0106 & P0172 codes

[InMSWeAntitrust]

Car just recently started losing power when accelerating; stalls out sometimes when turning and slowing down at the same time.

Car's history from most recent to least recent:
Today - Replaced air filter, looks like the old one was stock (from '96 )
Couple days ago - went to AutoZone and got the printouts saying Codes P0106 and P0172 (Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem , and System Too Rich (Bank #1), respectively
~1mo - Spark Plug on cylinder 1 starts coming loose, turns out the wire had just gone too far into the head cap; hasn't repeated itself.
~5mos - Oil Change
~1yr - New Transmission


Any and all help is greatly appreciated; To get this fixed and do a tune up while at it will cost ~650.

hello
check the vacum line going to the MAP sensor to the madifold. if the vacum line is cracked or not connected the ecu thinks you are at wide open throrrle.
the engine will run rich.
i have seen this on a few camrys.
