Customer Question
I have a 2002...

I have a 2002 trailblazer and it is running rough with code p0106 and p0014. I replaced the MAP sensor and cleaned the throttle body. Changed fuel filter as well. It boggs down when I try to barely tap the gas pedal. Also when I floor it to 3500 rpm the engine makes a growl noise

Mechanic's Assistant: Are you hoping to fix this yourself?

Yes

Mechanic's Assistant: Great! What have you tried so far?
