My 1999 Lincoln Town Car runs really rough after I get it washed...?

Whenever I get an underbody wash on my car it runs really rough. It has poor acceration and the check engine light comes on. But after a few days it runs normally again. Have no idea what it could be..........HELP
Look at your air intake. Thats a mass air injection system so if water sprays into the intake somehow it will get the MAF sensor wet and the injection will go haywire and throw codes until it dries out.
