i just had my engine pressure washed on my 1986 mustang by one of my friends who is really experienced with doing that. After i got my car back from him i have been having a rough idle while at a stop and when i go in reverse the engine stalls out sometimes. anyopne know of anything that could be wrong or what i could do to fix it?

 

wrong forum, try posting in the generation specific forum

 

anyone know of how i can fix the rough idle i am having from having my engine pressure washed?

 

Uh oh...

Pressure washed + engine = not good. Check for any vacuum leaks and look at your plugs....but yeah the 5.0 section will be more helpful.
