lately it's been giving me fits. Sudden loss of power and major drop in fuel mileage. Scanning it first showed MAF. So I replaced it. Then showed MAP so I replaced it. Then showed lean on bank one O2 so I replaced it. Now shows P0496 P0106 P0171 P0496. So I'm waiting on the evap solenoid ( I pulled mine and it had a lot of powder in it and was in the open positition also had no restriction) to come in today to replace it. Im not sure if it should be open or closed. This is my work car and this week I have about 1900 miles of driving to do. So I really need to figure it out. I have tried to find any possible vaccine leaks but no luck. Where are common problems? Thanks y'all. Btw it's a 2006

 

Stop throwing parts at OBDII codes! The codes do not mean what they seem to say! They give you a starting point on a diagnoses tree that can be found in a Service manual.

Check your PM for info.

 

Thanks don got it
