Many many prayers!
I ended up replacing both O2 sensors, FPR, plugs, 2 oil changes with Shell Rotella T6 5w40, running the BG tri-fecta through and what seemed to make the biggest impact was the timing. I had double checked about a few months ago according to the FSM and it was spot on. I double checked it again on Monday night and it was jumping between 3º and 10º BTDC. I dialed it in again to 3º BTDC then tested on Tuesday. BAM! I passed. Not sure exactly what did it but I may have a bum timing light or I just don't know what I am doing.
On a side note, I tried to test at the Northglenn testing facility but was turned away due to the condition of the testing tires so I drove to the FT. Collins facility to test with my 315's on because I was told that they have a machine that can test 35's. Thats not the case but they still tested it anyways. The tech stopped the test half way through and I was told that my oil pressure gauge was going too high during testing and my truck was unable to complete the test due to it being defective. I was told by the tech that your oil gauge should never move even when driving.
I was much perplexed by this explanation. I was then told to sign a paper stating that my truck was unable to test and was defective due to a high oil pressure gauge. I rudely told the gentleman that I would not be signing any paper work stating that my truck was defective and unable to test. I asked if I could have a copy of that paper and he in a similar rude fashion told me that I was not intitled to a copy because I did not sign it.So on Tuesday morning I drove to the Sheridan station, no wait at all and the truck passed no problem with my 315's on and no mention what so ever about a high oil pressure gauge.
This week I will be writing a letter to my state rep describing the emission testing issues and discrepancies and what actual costs go into the entire emissions process and why there needs to be a more standardized process and better training for emissions test employees.

Why should they care what your oil pressure gauge does? Strange. Denver emissions testing seems like such a colossal waste of time and money for people. It must bring in a lot of state revenue or something.Many many prayers!

Wahooooo!!
That’s some BS about the oil pressure. But wahoo!
