And the trouble codes that led you to throw parts at it, were what?

the codes that come up on my car are P0102 MAF or VAF A Circuit Low Input P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2) P0443 EVAP Emission Control System Purge Valve C Fault I went to get it inspected and the inspection staion told me it failed the test due to the gas cap and i returned the next day with the gas cap and they told me that its not ready for inspection. And when i shut the car off the only codes come up are the P0102 and the P0443. I changed them and the light is on and i asked the Service Station at the Chevy Dealer and they told me i have to get the codes reset and drive the car around and put any where from 50 to 200 miles on the highway and stop and go traffic area and the computer should be reset itself. Ill let you know how it goes after i get it reset.
