Customer Question

i
JA: Sometimes things that you think will be really complicated end up being easy to fix with a GMC. The GMC Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: 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
JA: Are you hoping to fix this yourself?
Customer: yes
JA: Great! What have you tried so far?
