did some research and heres what I found. but I still have a couple of questions

P1133- A/C pressure sensor high volts or o2sensor bank 1 sensor

Does this mean my front passenger side or front driver side is going bad?

P0140- o2 sensor no activity detected bank 1 sensor 2

P0160- o2 sensor no activity detected bank 2 sensor 2

the second 2 codes are because of running no rear o2's correct?

That code is for the driver side front O2/insufficient switching which means the O2 is not switching enough between rich-lean and vice versa.

From the manual: The PCM determines that within 100 seconds the HO2S lean to rich switches are less than 30 and rich to lean switches are less then 30.

More than likely you need a new O2. Did you just install long tube headers to the car?

P0140- o2 sensor no activity detected bank 1 sensor 2

P0160- o2 sensor no activity detected bank 2 sensor 2

Correct. you need either O2 simulators which plug into the PCM side connectors for the rear O2's. However they are not sold new anymore so you you have to search for a used pair. Or, simply have the codes turned off by someone in your area who has either EFILive or HPtuners.

headers were put on the car approx. 800 miles ago. The passenger side was put on about 4000 miles ago and it was just transferd from the old manifolds,guess its time to change the driver side now. I have no idea how many miles it has on it but I have read on here that when you put headers on these cars they will eat you o2s.
