Message:
I was running thru a HEAVY rain storm here in Middle TN yesterday. Roads had a lot of water, and I was running thru about 4-6" of water for a short period of time a few times. During the drive thru the last bit of water, my '94 3.9 threw a code. Parked the truck and it read 21, O2 sensor. Since then, the truck will run rough, blow lots of smoke, esp during long idles and strong acceleration, and after a while, the CE light comes on, again throwing a 21. Could it be the water damaged the sensor or could it be something else. When the CE light comes on the truck seems to run somewhat better, guessing its in some kind of limp mode. Any information would be appreciated. Thanks.
