New issues with her or old? You’ve been through a bit yourself lately so I hope you weren’t both laid up at the same time?

Just a continuation of old ongoing issues for her. As for me I'm invincible!! Til I die anyway lol.
On the way home I was alone, and I took a sharp curve jumping on the pkwy. I did notice it handled alot better, but I have 265 70's so there's still a little sidewall flex. It would've handled alot better with some 22's--but I sold them--don't regret it either!

So possibly a vacuum leak? Could that also cause a really low idle?

Usually a vacuum leak will cause a higher idle.

Wouldn’t it also result in negative numbers on the STFT too?

No, with a vacuum leak more (read: unmetered) air is getting into the system. System has to add fuel to compensate, so positive fuel trims.

Your right. I’m done for the day. I’ll see myself out…

are you driving it during these scans or just holding the gas? being under load can change things, vs revving it.

the ltft are rich, might have a vac leak or the tune was set up to be rich.

the o2's look good as far as being very active, the test for them is go wot and bank 1 and 2 sensor 1 should lock in around 930's and stay there the whole time your wot.

misfires, well ya got a cam. why tuners delete the multiple misfire code from the tune. or the cel would be flashing all day long on most larger cams.

I’m wondering if the reason I keep getting the random misfire code on my Denali is the cam then. Although it didn’t do it for over a year, now it does it on occasion.

Does this thing have a MAP sensor? How does that play into the fuel metering?

It does and I replaced it--no change.

might when it gets hot. that pesky p0300 code should be deleted with a cam. the lope and chop is pretty much a misfire, sooo lol you have a blower on that truck too? might need new plugs if running copper core plugs, they only last like 12-15,000 miles. puts you back on the old school days of a tune up once a years.

Hot AF today, and Mon/Tue is gonna be hotter, so if course I cleaned my front carpet and front seats. Carpet is much better, but not what I expected. I was gonna get the oem rotors cut--@$25 a piece, but then saw these--
I also ordered some GM abs sensors--so I thought. Looks to be only 1.
