I also got a P0122 and P0123. These are TPS Circuit A high and low? I have just replaced it with an adjustable one set at .54.

Looks like TPS Sensor trouble.
P0122 = TPS A, Low Input
P0123 = TPS A, High Input
BTW- Is the Check Engine Soon or MIL light illuminated?
Since the two trouble codes seem to contradict each other you might try resetting the system and see if the indications return.
Regards,

I looked up those codes on a '96 Vette (I wasn't sure if you were getting those codes on your LT1 or your Mossler) and got the following:
P1133= H02S (sensor) 1 Insuff. Switching
P1153= H02S Bank 2 Sensor 1 Insufficient Switching
Sounds like you might have some sort of O2 sensor problems. I think the H means you have heated O2 sensors. Hope this is some help. If you have a scan tool that you can watch the live data you could watch what your O2 sensors are doing. Good luck.

Where are these sensors located? (B/4 cat, after cat?) Are both failures in the same bank? Are they hooked up? Have you messes w/ the exhaust lately?
HO2S = Heated Oxy Sensor. You will have 3 or 4 HO2S's. ODB2 only use heated O2's.
Could be as simple as bad O2's but w/ 2 failures,... seems like something else is going on.

Thanks, guys. I had the headers put on about 2 months ago, that has been the only exhaust work. I am going to try and tackle this problem this weekend.
