Hey guys, I finaly figured out how to pull codes from the 93 Ex and need your help on figuring out the next step. I get no CEL at all but getting crummy gas milage.
KOEO
121 TPS voltage out of range
CM
111 Pass
KOER
121 TPS voltage out of range - inconsistant with MAF
125 TPS voltage lower than expected - fuel control
173 O2 sensor not switching - system is/was rich - Ho2S System indicates rich
Ok so from these codes guys/gals I see that I may have either a bad TPS running rich and an O2 sensor that is bad.
Just looking for clarification I guess.
Drive 30min one way to work everyday and gas $$ is on the rise so looking to get all out I can.
MAF is freshly cleaned, KKM filter, had done the TPS mod but could never get it down to .95 it was at .99 . That is as low as I could get it to go.
Thanks for any help that can be given.
