P0171, have you tried looking for a vacuum leak?

 

[bigt61]

Stick a spacer in the o2 Sensor bungs then screw the o2 Sensor into them

I had to do that with my Ford

Is it a 4wd? If so sell it to one of us Northern GA boys. We don't have to do emissions tests up here.

 

[HVACGuy]

On the P0420, that's a toughy... Could be lots of stuff. Any exhaust leaks? Check wires and connections?

 

[Mr. Booshie]

If you spend x amount of money and it doesn't pass they waive the test.

Or if you are of a certain age of older you also don't need emissions.

Clean the Mass air flow sensor. Reset codes. I had this happen to a Buick once was running lean because the MAF was dirty.

Or down my way.
