Replaced air filter, sprayed carb cleaner to clean it out, seems to help some, but still runs high idle.

Any other ideas I can try before I take it to the mechanic shop ?? Thanks

As mentioned before, check the IAC and clean it if necessary. Your symptoms sound similar to what I had happen on two of my Fox-bodies and cleaning the IAC was the quick and cheap fix.
