Weird stuff just happened. I cleaned up lots of connections ytd but it would still have this weird idle bumping between 550 and 600 rpm. This morning after commute I felt fancy and turned on 4wd and 4 low. All engaged, no problem. Put back in 2wd and the weird idle continued.
In the afternoon, on a quick errand, the first time in months, the idle is rock solid at 550rpm. At least at the first traffic light. The second traffic light the truck stalls on me after 2 minutes idle. No surge, nothing. Turned right back on, no hard starting. I drive around the corner, put it in park and again. 10 seconds in, truck stalls. I realized I just passed quarter tank mark.
Off to patrol station, fill to the top. Now rough idle is back but no stalling. Just idled in the parking for 5 minutes and it stays on…
Pretty much sums up my day
