Failed emissions and it said car was running to rich. What do i need to do or check to fix this?

 

Well most common causes of running rich are.

exhaust leaks before the 02 sensors
bad 02 sensors
misfire
bad EGR
bad TPS

Also since your running a powerdyne has the car been tune?

I got a code for a bad tps so it might be the problem. I replaced it right before the test and unplugged the battery so what do i have to do to reset it?

 

You might have to drive around a few so the pcm can adjust with the new TBS. Also what's your engine temp running at? I've notice when I run my fans at 160 the car runs rich. When I switch it back to stock setting it doesn't run that rich.

What were the exact test results for CO, HC and NOx, and what are the pass/fail limits?
