driving a 97 k2500 camper special, 4l80e with 454 vortec couple days ago I got in my truck after work and noticed it would stumble when hot, 100C no problem but a little bit warmer and i would have issues. always under load during acceleration. got home and idled in drive and it felt like an obvious misfire, RPM would drop to about 500. pop it in neutral or park and no misfire or stumbling, its been confusing me since in the mornings when i pull it out the garage it has no problems all the way to work (5 minutes highway and 5 minutes city) but end of the day and evening- same issue bought the truck with 268km now has 276, oil change every 5000k. did fuel pump (48psi at idle now) FPR, distributor cap and rotor, plug wires and plugs, ran seafoam through the intake and in the fuel tank. ive heard of distributor gears going south but id assume then i would have the issue when cold too. runs like a top at any temp below 100C, no engine light, plugged the scanner in anyways and no codes whatsoever. any help is appreciated, looked through forums for a couple days now but nothing exactly like what I'm experiencing. kevin, -
How's it going , new to forum and hoping someone could shed some light. I have a 2019 silverado custom 5.3 w/ 6 speed trans with about 37k. A month ago the truck threw error p0741, it would Rev high and not want to shift so dealer replaced tcm and new fluid. A few weeks past and code comes back with trans temp running around 215* when it did so dealer replaced torque converter and said it was good to go. I took for a extended drive of so.e city and a Lil hwy for around d 1hr and Temps climbed to 225*. Is 225* high? Doesn't seem normal and dealer is saying they. Ant find anything wrong 20210429_195723.heic -

2015 chevy 1500.. 3400 miles. A couple of times the heat didn't work. It always did "next time".. the other day I had to take a 3 hour drive.. it didn't work the whole way there...stopped for an hour..headed back still with no heat (it was 42* so it was not pleasant) Took to dealer - they said they cant find anything wrong, of course, and of course the he was working fine. Its only done this a couple of times in the past 2 months now. Anyone experienced anything similar? It blows out air, and it will adjust the fan speed properly (or what I'm guessing WOULD be properly if it was blowing out heat) based on the temp of the cab. Even when taken off of auto and just turned temp to hi and fan speed up, with AC button off, it was still blowing cold air. Any ideas? Could it somehow be user error? (doubtful) Also when the AC button is on, even when its on heat, is the AC really still running? seems dumb that lights always on even when you have the temp high and its blowing heat.

I purchased a 2014 gmc 5.3 with 80k. the lifters were all replaced under warranty. soon after i noticed 10 psi oil pressure after driving 25 min on highway. dealer replaced oil pump still has 10 psi after 25 min of driving. when i first start up its at 40, oil pressure goes to 70 when rpm exceeds 3500 rpm. oil pressure starts to drop to 20 after 10 min and seems fine. after 25 min it drops to 10 on guage. i had oil pressure checked with mechanical guage and confermed guage is accurate. i asked dealer to che k the screen under oil pressure switch they said it was clean. at this time dealer says nothing is wrong due to specs at 1000,2000,3000 rpm. i called gm customer care and they said to get different dealer to look at. i did and they confermed rpm at different rpm and charged me 118.00 gm customer care did nothing to help me out. i have never seen any truck with 10 psi at idle. does anyone else seem to have this issue?
