What’s the fuel trim doing on this truck? Does one bank goes full lean and the other goes full rich as soon as closed loop starts?
It is good on both sides. Also, as I have been driving it, now about 400 miles, the hot starts have significantly improved and the exhaust smell has been a lot better as well. I didn’t notice it being smelly at all the last couple days.
One thing of note is that before I replaced the radiator I was getting a code for temperature out of range as soon as I would drive it up a long grade. It was getting up to just above 210 degrees and the code would hit. New radiator stopped that. However, one drive earlier this week before the engine was fully warmed up, I got that code again. I drive at idle about 2 miles downhill to get to our front gate. It popped the code when I stopped to open the gate. I cleared it and it didn’t come back on the 10 mile drive to my son’s school with a 3000 ft elevation gain.. I have driven it since then and it hasn’t come back. However, I am going to change the sensor.
With recent good behavior, it (the red one) has now been promoted from the shop to my driveway and it is taking some drive time from gold one. This will allow me to finally remove the headliner in the gold one(get it recovered) and address the leaky sunroof.
