2001 Grand Cherk 4.7l
Got a CEL after hitting seriously rough patch of road and checked with a scanner. No code. Watched fuel trims, and ST Bank 2 bouncing from -2.0 to +33%. Bank 1 ST normal, and both LT normal.
Disconnected battery to reset CEL and hope the next time a code wold be present.
CEL on again, and again no code.
Any thoughts on why CEL coming on, but no code is setting?
Thanks
