Question: My f350 351W engine failed Ontario emission test on the slow speed idle. The co% was to hi. Limit is 1.2 and I had 3.09 out the tail pipe.
Any ideas? Just put a new o2 sensor in and engine light not on and no codes.
One suggestion was if air pump is putting too much oxygen into cat at idle this may be throwing the o2 sensor off? What would control that or is this not likely to be my problem?

 

Just bought a 03 f150 v6 and front bumper and grille are smashed. Any suggestions for new front bumper like Street Scene that can dress this truck up? I'd like to lower the truck too. Who makes cheap body kit stuff?
