firebirddude98

98 v6 firebird, cable driven throttle body. changed the fuel pressure regulator after almost a year of driving it with the old one leaking fuel into the vacuum line. after driving for like 4 days, now i have p0122 (tps low volt) and p0422 (catalyst) showing. reading from wires on tps says it's good, so what should i look into?

Look into the forum that may give more help....Like tuning and diagnostics

check your ground wire if you haven't already. did a quick google search and that seemed to be a common problem.
