[89lxdriver]

ya. my car was fully warmed up when i took it after i changed the EGR. i havent changed anything else on my car.

There are a lot of things that you can do that might help. Try the air filter and pcv valve first. Since you had a "major tune up" those may have already been changed. O2 sensors can also cause problems. Pull the codes and see if anything comes up.

how would i pull those up? i need to be able to pass smog by july 20th or else bye bye stang!

i actually know a few shops in sacramento that will pass you regrdless of your actual emissions. few bucks in there pockets a slip later and your all set

[89lxdriver]

really? i live in daly city. how would they do that if its in the computer without any manual entry?

[89lxdriver]

someone help!!!

[lammy]

hell the first thing you should do is move out of that communist state and go somewhere where they don't have emission tests-thats the biggest crap i have ever heard- are you burning any oil what so ever?-do you have blue smoke coming out the tail pipe?-if so you may need to do a head rebuild-if not then do what droptop stang and find another shop-don't stick to one try several other smog shops people are hurting for money and most shops will look the other way

Most of the time, failing for NOx is due to a bad or poor performing catalytic converter.
