Okay I just bought a Ws6 2000 The car is clean and the guy who I bought it from had lots of F body cars built them over 1000hp daily driver cars he also has. I bought this car with long tube headers and a tune also has a y pipe. But He told me he tunned out the headers so it should pass admissions. Any way this Morning I turned on my car and didn't let it warm up I started driving kinda quick to school the check engine light came on and these are the codes it gave me were
P0135 02 heater
P0155 02 heater
P0530 A/C refrigerant sensor
P1637 Generator terminal...
Can this be all one problem or are all these things bad.!. Please help....

 

these links might help. But my guess is when he "tuned out the headers" some stuff has been forgotten. O2 sensors can throw up a lot of codes. My buddy did my car and missed a couple while deleting my rear O2 sensors so i still get a code every now and then. I am going to have to go back in and investigate.

P0135 and P0155
