Loping / rough idle. OBD codes indicating lean banks and MAF issues. Discovered faulty intake manifold gaskets and replaced. At same time, cleaned throttle body, replaced MAF, Knock sensors and knock sensor harness. Performed TSB |
| 117000 mi US $300 |
Car was throwing emissions and MAP/MAF general fault codes. K&N Filter caused fouling of MAF sensor, previously replaced in December. Replaced PCV valve (maintenance $20), and MAP sensor first, since MAF had been replaced so recently, but this did not clear the code. Replaced the MAF a second time, and this fixed the problem. |
| 118000 mi US $120 |
"Gross Emissions Leak" error code intermittently came on. Replaced with factory gas cap (top recommended fix) and retested. Code came back, replaced Purge Valve Solenoid for EVAP canister / system. Dirt had gotten in the valve and prevented proper operation. Somewhat common on the GMs from this generation, both pickup and SUV. Pickup has a relocate kit available from the dealer to remedy permanently. Light has not come on again, yet. There has not been a cold enough day to test the system since the repair was completed |
| 128000 mi US $2000 |
Having trouble starting vehicle. Diagnosis revealed low fuel pressure. Tested Fuel Pressure Regulator and determined to be faulty. When replacing FPR, discovered crack in fuel rail bracket preventing proper install of new FPR. Removed fuel rail to replace and discovered leaking fuel injector. Decided to replace all eight (8) injectors at this time as all hold down clips were rusted and one was leaking in addition to the fuel rail and the fuel pressure regulator. |

Charcoal canister vent solenoid failure Idler pulley failure |
| 153200 mi | Repetitive evap trouble codes are a way of life for this vehicle. This time a thorough cleaning on the fuel cap may have cleared it up for now |
| 154000 mi US $900 |
Fuel pump failed after only 50,000 miles. Pump and filter replaced. This did, however, also fix the repeated evaporative codes that the computer was throwing for the last couple of years |
| 163000 mi US $700 |
Camshaft position sensor check engine light intermittent |
| 169000 mi US $600 |
Cam position sensor fail. FYI. Sensor is buried under the intake manifold at the rear of the engine. Poor design causes this $70 sensor to balloon to $600 to repair |

Driver side oxygen sensor upstream from the catalytic converter failed. CEL on. Replaced both upstream sensors |
| 184000 mi US $125 |
