I had brought my supra for the regular do-it yourself car wash but this time i decided to do an engine wash also and i realize now that was worst decision i could've made because now the engine is running on 2-4 cylinders instead of the should be 6. It won't even idle well enough to drive it to the nearest shop and when i opened the spark valley i realized that there was about 1/2 inch of water sitting on top of the sparkplugs in the spark valley. Even after sucking all the water out and replacing spark plugs with new ngk's and i also replaced the wires with new msd's and still it is not running as good as if i didn't reaplce anything so i'm guessing it might be that the coils are gone bad or maybe even the maf meter because when i unplugged the maf it ran the same unplugged as it did plugged in so give me your opinions on what i should be replacing.
