Question about 2004 Chevrolet TrailBlazer
When i am at a red light and i push the gas pedal, my tb revs really hard but wont gain speed the way that it should and it is killing my gas mileage and i had a code for the thermostat. i replaced it and now i have a code for po172 system running rich bank 1?
Po codes are a default, reset the computer by removing the battery cable for 10 mins.
this will reset the comp back to 0's.
