Took a 5 hour round trip last weekend to pick up the 1/4 beef I bought from a friend. On the way home, I had some rough idle issues. Watching the live data, the bank 1 (first 3 cylinders) STFT went way negative during the rough idle. Like -15 to -18%. Once the idle smoothed out, it returned to numbers that matched the bank 2 STFT.
I dumped a double dose of Seafoam in the tank this week and it's not making much difference. Today I was doing a visual inspection of everything and saw that the #3 injector is cracked. It's not leaking, just a split in the body.
Tonight I ordered a full set of the remanufactured Bosch 4 hole injectors that are supposed to be factory matched and have a lifetime warranty.
Slowly getting this thing in order
