Won't stay in closed loop
While trying to hunt down a low power problem I'm using a scanner to monitor stuff while on my 85 mile ride to work. I've noticed that while cruising on my 85 mile ride to work, each time I hit a hill and need a bit more power, the thing comes out of closed loop operation. I realize that WOT will do this, but it never shows WOT. I have noticed that the O2 sensors seem much more erratic when in closed loop than on my pick up, but that look like they're working. All other sensors look like they working also. No codes set. What else would cause open loop operation while totally warm.
