I have 94 LHS that always has white smoke coming from tailpipe (not alot) just enough to were its noticeable.I thought maybe bad headgasket so I had all headgaskets replaced and heads shaved. I have not put water in this car in like almost a year.I dont think im losing coolant butThe smoke is always there plus Im getting code 32, 41 and 33 but this is probably were I had my a/c unplugged, I usually do unplug it in the winter months to save gas.
Do you
have the same problem?

It must be pretty bad for you to have both heads done. Water itself is a natural byproduct of combustion and the more water you see dripping out of your exhaust pipe the better, that is a sign of a healthy engine but it shouldn't be white smoke after the engine is good and hot. The code 41 is a code for the vapor cannister purge solenoid, so if its open all the time and the cannister has too much water in it, it will be constantly being burned through the engine uncontrolled as far as the PCM controlling it and the times and temperatures it is supposed to be purging at. That would mean the engines intake could be overly open to too much vapors being purged, especially if the cannister is no good, soaked, or maybe even has water draining into it whenever it rains, filling it up. You could try taking the purge hose off the intake, plug the opening and see if it makes any difference. Re-connect the a/c system, clear the codes and drive it around to see if this code comes back or if the smoking stops, if the code 42 is there the check engine light should be on. Good luck, let me know what you find. And see if the cannister has water in it and that the PCV valve is ok and attached properly. Ok The a/c clutch, the compressor controls and the codes you have are all on the same power circuit, they have a common power source, the fuse for all 3 may be out if any of the connectors touched ground, and disconnecting the a/c may have led to an answer.
