04 fx4 fresh plugs and coils. Idles very rough and goes dead when put in gear. Thought it was a vacuum leak but I sprayed it down with brake cleaner while engine running and it never smoothed out. Put air in vacuum line to see if I could hear or feel the leak but nothing. Scanner shows misfire on cylinder 2 and bank 2. MAF is at 0% with engine running. I'm totally stumped and don't know what it could be. Everything seems to point back to vacuum leak but I can't find it...any suggestions??
