grysrt I dont know if this will fix your problem or not , but may help.
Joannes QC has long tubes with no cats, with sims, and has usually had no problem passing emmisions.
well it has sit for almost six months, and the other day she drove it to get it inspected. On the way there no engine light.
when they hooked up the machine it wouldnt pass, 02 sensor not ready and evap control not ready.
took it into the dealer today and found the ppump going bad on the truck, had a couple codes in the computer, no cel by the way has shown up:dontknow:
but they told her in a round about way the evap system affects the 02 sensors causing faulty readings and may not show up as a cel light.
Replaced the pump and all is well now.
so you may just have the dealership check out the evap system jsut in case.
and no the dealership didnt have any problems with her mods, headers, no cats and so on, well he couldnt work the floor shifter
but then my dealer gets a kick outta our trucks

the guys actually love it when mine rolls in
