Kind of a weird one here. I did search around on the forum to make sure I wasn’t double posting, but couldn’t find anything quite like what I experienced today.
A little background:
2017 Ram 1500 Sport 5.7 Hemi
~85,000 well maintained miles
Have always run the “recommended” 5w-20 changed at 7k intervals
Bone stock (only things that may be slightly different with the “sport” than other trim packages is a mopar CAI and “performance” exhaust, but again both are original to truck)
The only existing issue that I am aware of on the truck is the leaking exhaust manifold. Believe mine is only on the passenger side for now. I have had the ever so common “cold tick” for about 20k miles now (of course it started just outside of warranty) and as this truck is the 2nd 4th gen 1500 I’ve owned with the same issue, I’ve just chosen to ignore it.
ANYWAYS
I’m hoping someone could provide some insight as to how to go about diagnosing the issue I experienced today.
I can only describe it as an EXTREMELY rough idle. I had been driving for over an hour already, so it was all the way warmed up. Put in in park to get out and get the mail upon getting home. As I was sorting through junk mail at the end of the drive, the truck began to idle very rough. Far more than a miss. RPMs would dip to nearly a stall, and fire back up to over 2 grand every 10 seconds or so. Also sounded like some knocking and other awfulness. Feathered the accelerator to no effect, like it wasn’t even there. It sounded and acted bad enough that I was truly worried I would be pushing it the rest of the way down the driveway. No trouble lights on the dash at all. Shut it off, checked the basics (motor still contained oil, nothing is on fire). Went to start again, same rough idle and no throttle response. Waited about 30 seconds, started again….no issue.
Curiously, instead of heading down to the house like I probably should have, I backed out of the drive and drove about another 5 miles to see if the issue reoccurred. Multiple times stopping, parking, idling, and even cycling the ignition. Could not recreate the issue.
Drove back home and hooked up the code reader, I use v-linker with an app that displays all ELM327 data. No DTCs whatsoever, like the truck never even knew anything was wrong.
Just curious if anyone here has experienced anything similar and if so had any luck diagnosing.
Thanks in advance!
