2002 C32 washed motor 3 months, miss at idle
My C32 misses only at idle and only cylinder 3. It also keeps CEL on with b1&2 #2 sensor heater circuit fault.
I unplugged all four o2's tested heater circuit voltage all read 8.35 volts unplugged and plugged.
I swapped cyl 1&3 fuel injectors, coils, spark plugs and wires, still #3 and only idle. Just touch gas peddle no miss.
Any ideas?

I started it cold and right to car wash, 3 miles. Waited to do engine about 5 minutes and tried not to spray directly on top of engine. I had just replaced valve cover gaskets and trying to clean sides of engine. I've taken the ecm out and apart No sign of moisture stains. I've replaced all four O2's. It's been going on 3 months with it not being driven.
