Help..pushing 150K on my 04 Chevy Trailblazer LT and check engine light is on. Advance auto ran a code check and I ordered an OEM 02 bank1 ($44)and MAP sensor ($65). Where are they and can I plug in myself (I'm very mechanically inclined)? Thanks in advance for everyone's help. Best truck ever! I'll talk about ticking next...pretty standard issues like we all have. Rob [email protected]
