I am back in the (3800) v6 fbody game! Hopefully this post is gold to someone later.

Also check your tune since running the aftermarket cam, and A/F ratio. I’d figure you’d run richer in the colder weather but who knows.

I know you probably did but did you change the fuel filter? Sock pump along as it’s above 40psi you should be fine. Maybe run some 91 or 93 octane through it. If you have Hptuners check the graphs to see if it’s running lean. Also scan while doing WOT runs and monitor the fuel pressure.

I have HP Tuners, but I would say it isn't running well enough to go get logs really. I could get some idling, even though the idle is weird.

You have a wideband O2 gauge?

You have a wideband O2 gauge?

I don't have one. I planned to buy one once this motor is broken in and ready to go before we turbo it, but it looks like I need to pull the trigger here soon!

Yeah they come in handy, I’ve had my PLX M-300 for 23 years now, just replacing the wideband o2 sensor ever so often. Which is only $35 . If mine ever goes out I’m getting a Ballenger wideband since the don’t make the PLX M-300 anymore.

Also I’ve learned not to trust the stock O2s, I just use them to tune for long and short O2 trims.

Here’s a log of it idling with a few throttle blips.
one of the o2 sensors seems to be off the reservation.
LTFTs both pegged at 25.

Your timing is low at 15 degrees, and looks like Your O2’s aren’t working, are you getting any KR?

[ssms5411]

I would think your O2’s would be higher at idle, at least 600-700 at idle and go up to 900-920 at WOT. Let me check some of my logs on mine.

Okay your O2’s look fine but your timing is low. Can you send me your tune , I’ll PM you my email.
