Found fuel for 2.16 in west florida. It 2.69 around indiana

 

Sleeping in it. 42 degrees outside is good sleeping in truck weather.

Sound like EVAP codes to me. Stupid useless system. It's good at cleaning out your wallet in states that test for emissions, though ...

 

I get to try and fix a "small leak" on a '06 Impala today. I'd better find some blood pressure medication ...

 

 

Ahh correction - those are lean codes, bank 1 and bank 2. WTF? On a '10 ???

Both banks lean. I'd start by testing fuel psi.

 

Evap isn't all bad, for one thing your fuel doesn't go stale as fast. Very easy system to troubleshoot and fix in my limited experience with it.

Yes bank 1 and 2 lean truck is running fine

That's what I hate the most about OBD-II. The thing runs fine, so the light is on due to emissions. Now if you live where they don't test, then it's all good. But, if it's sticker time, now you've got to waste time fixing it. That burns my ass ....

 

 

 

 

 

Every EVAP system I've tried to fix was like finding a needle in a haystack. Without a bi-directional scan tool or a smoke machine, it's a matter of guessing correctly. I'd have better luck getting struck by lightning while winning the MA state lottery at the same time ...

 

I might try to rig up my 2-stroke leak down tester on the filler neck & see what I come up with. Finding a 1 psi leak should be fun even still ... Might just throw a gas cap at it and hope for the best ...

Gonna suck if you find out E85 is causing system problems even with an FF truck. That won't be good news for anyone.

 

Hope it's something simple.

 

 

Dump in a few cans of seafoam and BG44K and run it hard and hope for the best?

I am thinking dump O2 sensors and add some headers. No inspections here

Nice - you're lucky!

 

Good news for me - just found the codes on that Impala are bank 1 sensor 2 codes (o2 sensor).

 

Gotta love OBD-II! Sensor has no bearing on how the engine runs, but because we live in MA, the 85 year old owner on a fixed income gets to shell out $68 for a new one (wiring and fuse good). :nonod: Needs a sticker by end of month.

    • The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.
    • So I purchased the Range unit for my 2026 and I am seeing different locations suggested for the ECM . Can anyone confirm wither under hood, left side or right side or behind the wheelwell?
    • Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that. 
    • "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
