South West - shops in AZ

I'm having some problems with my 91 civic and i was wondering if anyone knows of a good reputable shop i could take it to for some diagnostics.

What kind of problems are you having? I used to take my 1990 CRX over to Import Power House. http://www.importpowerhouse.com I've heard some good and bad stories about them, but they've been nothing but great to me. Dave and Ramsey would probably still recognize me if I went in there, and I haven't been in over 2 years. lol
