Any Suggestions?

I have a small problem that just recently started up with my 3.3L V6. The problem is that everytime I start up my car and switch it into drive or reverse, the car feels like it lacks power, it sort of lags and light gray smoke started to come out of the tail pipe not blue or black. I have the tcc disconnected but I really doubt that is the problem. I'm thinking it could be the o2 sensor but I dont get any codes for it. Any suggestions as to what might help. Also where is the Knock sensor on this car, its a 1993, I got a code for it and want to replace it. Thanks for your help.

the knock sensor is screwed into the block. right side of the car, near the oil filter housing. DO NOT CONFUSE THE OIL SENDER WITH THE KNOCK SENSOR! the oil sender screws INTO the oil filter adapter. the knock sensor is IN the block. it's a large round sensor, approximately 1" to 1 1/2" in diameter. you have to squeeze the connector that goes to it , on the sides and pull the connector off. you can then reomve the sensor with a wrench.

sounds like some parts are gettin old.. i would check for brittle vacume lines / posibly a leak. also when was the last time you did a tranny flush? with the smoke ... its prolly just moisture that has been built up in the tail pipe over the night, not much to be worried about.
