Next up, the inevitable mechanical gremlins that show up before any big trip.
On my drive to work the next morning, the truck was running ok, but had a very slight misfire. After work, that misfire turned into a full on dead cylinder, with a flashing SES light. Code was a misfire on Cylinder #3.
Since I was almost packed for our big trip, I had most of my tools and spares on board.
I swapped out the plug, wire and ignition coil with no effect. I didn't have a spare injector, so I just swapped #1 and #3. The misfire followed the injector, so I guess it's time to upgrade those!
The L92 injection system I'm running uses very small (30lb/hr) injectors. I decided to swap out the entire set for a set of GM 12613412 50lb/hr injectors. They're OE on L96 flex fuel engines, so they should flow plenty for my needs, while still being available if a replacement is needed. No photos, but those were swapped out and the ECU calibration updated with the new flow rate. The idle is much smoother now, I'm guessing these original injectors weren't working too well.
