Hey everyone I've just moved to Denver, Colorado and went to get my 94 FJ80 registered. I had to go get my emissions tested and I failed the NOx by .7 GPM; i read 4.7 the standard is 4.0. I need some advice on whats going on! If i can do a quick fix by running better fuel/ spraying the MAF/ or something else. Other than that i need recommendations. 1. Where are the land cruiser specilists in denver area ( ive heard slee is good in golden). 2. Quick fixes to pass. Thanks.
