2 hours ago I was driving in the rain, all of a sudden truck runs like junk. My SS keeps shuttering when i gas, hesitating like wants to stall, very sluggish, smells like gas, and rough idle. In the past 4 months I've had this problem a total of now 3 times, at first O2 sensor was toughing tranny, was blowing black smoke and every symptom i wrote above, I thought that fixed problem but everytime i hit a hill i felt a slight shutter still but then went away, then a month half after it rains happens again the whole day from freeway to streets. Next day stops raining and whatever the problem was went away, I checked under truck for wires touching again but nothing. Another month and a half or 2 go by it rains, all of a sudden happens again all the symptoms stated above. I don't know what it is I'm so frustrated and mad. I heard it could be the bad O2 sensor, running rich, and or the knock sensor? Has any1 else had this problem before I need help Please.
