Failed again for CO. Got it down to 54. I’m gonna try to see if the smog pump is actually pushing air out (it seems to be pulling air into it fine). Any more tips anyone has would be very welcomed. It’s gotten a full tune up, replaced thermostat as the top o-ring was bad preventing it from getting to and staying at operating temperature. Now it does get to operating temperature and stays there. Cats are new but are standard cats (not California cats). Ran E-85 and that did wonders, but not enough.
Lastly, does anyone know if the ASV on the 91-92 models is the same as the ABV on the earlier model 3fe engines? I’m definitely getting frustrated with this whole deal. Had I known at the time of purchase that it had an emission exemption, I never would’ve bought it. (Purchased from an active rising sun club member). Sadly, I love the rig and know that if I sold it with current Colorado emissions laws I’d be liable if the new owner couldn’t pass.
