Emissions Question...

[Great-Kazoo]

DO NOT USE MMO, it's an abrasive (yes we can debate it just like WD-40) B&G Products, tha's all you need to know.
Crack off and spend the money on the 44K. HOWEVER do not go back for a recheck "after 30 min of driving" fill the tank up drive it on 25 or 70 until you need to fill er up. The 44K is cleaning the valves etc, all that shit may cause you to FAIL AGAIN.

Personally it doesn't seem like you've been on top of your maintenance with this unit. Now you need to spend cash, instead of nickel & dime'ing it, to get passed. ALWAYS do an oil & filter change b4 any emissions test, same for the air filter AND fresh fuel.

ONE ITEM everyone has neglected or forgot to suggest, you change it the fuel filler / gas cap. They test it and once again it's another $10 item you should invest in b4 a recheck.
Every auto parts place said to replace the gas cap, based on how many folks came in after a ET and said they would have passed if the cap had met test specs.

Bottom line, you wouldn't skimp on your guns, why skimp on your vehicles?
