Turbocharged400sbc update!Got the o2’s replaced today. Man they shove those upstreams in there, ended up being easiest to just pull the flares and inner fender wells. Everything went smoothly, Denso replacements are in.
Truck runs way better. It used to knock/detonate when applying throttle while cruising, which I’m assuming was due to it over fueling and adding timing because the Alcohol percentage calculations were so off and it damn near running on the E85 map. They were 65% before the o2 replacements, after an immediate refueling event, 100 miles of driving and another refueling event just to be certain, they dropped to 17%. I would still like to see them be where the ACTUALLY should be (sub 10%) but I will take it for now. Not sure if there’s anything else tune-up related I can do to improve upon that or if I simply need to recalibrate it.
I’m curious how the cold start is going to be tomorrow. This is how it used to be before any repairs, it got marginally better after the intake gaskets, but was still about 70% shit. Also smelled like a small engine starting on choke as far as richness goes and even puffed some blueish fuel smoke until it cleared up.
No big deal. Just sucks cause it's cold and I dont want to do shit when its cold
