Is there a good independent Q45 tech or shop in S. Arizona (Tucson or Phoenix)?

I've searched in the NICO forums and elsewhere and can't find a good reference for an Independent tech or shop in S Arizona. I see that Scottsdale Infiniti is frequently recommended for parts related questions, but only shops in Atlanta and another in San Diego are recommended for service. My wife owns a '93 Q with just over 100k. It has had intermittent rough idle likely caused by a fouled injector. I just recently became aware of the issue with plastic chain guides on the early Qs and am worried about my wife driving this car. We formerly lived in Seattle and near Richmond, VA. I was unhappy with service (cost more than workmanship) at the Infiniti dealers in both locations.

Thanks,Tom

Tom - I know of a place or two in PHX, but nothing in Tucson. Let me do some snooping.

Thanks Greg. Tucson would be best, but my wife is in Phoenix about once a week so that could work too. We would likely get the plugs and injectors changed out along with the chain guides. What else do you recommend we get done at that time? She loves that car!
