I will ask if he is willing to loan me one to see if that if the problem. Thanks to all for the help.

FT52,
The diagnosis of this fault (P1130 or P1128) is to:
(This is when the the air/fuel mix is so
lean the adaptation has reached its maximum
rich boundary.)
1a) Check the signal coming from the MAF sensor
1b) Check the exhaust system for leaks -- a leak ahead of the O2 sensor will cause a fault in fuel adaptation
1c) Check for air leaks in the intake air system
2) Check the fuel pressure (too low)
3) Check the volume supply of the fuel pump (too low)
4) Check to see if one of more fuel injectors are fouled on that bank.
(This is when the the air/fuel mix is so
rich the adaptation has reached its maximum
lean boundary.)
1) Check the signal coming from the MAF sensor
2) Check the fuel pressure (too high)
3) Fuel injector leaking
4) EVAP canister purge valve is open or not fully closed
Good luck!
