DAMN FORDS!!!
today my mother came over and we changed oil and washed under the hood (it was a mess)....
now its all clean,but it runs rough as hell,stalls,knocks and wont get out of its on way.
so i pulled all the coils found moisture on one of the coils so i used air to dry it and blew all the spark holes out.
blew out the injector,tps,egr,iac,maf plugs.

The 2v coils go straight down and if you put water in that spot it will fill the tube up with water and cause this.

The 4v coil on have a coil cover with a o ring seal, so they are more safe.

And with the pushrod motors the dizzy is right up front and of course moisture likes to get in there.

Avoid those areas and you should be fine.
