Have a few questions,

I just bought this car from a friend about 4 months ago. Its a 94 EX Auto with 148K miles on it. I have been having problems with the fuel gauge and so next month I am going to replace that myself. But I recently moved to Dallas, TX and were starting to get into the summer months. Can I get my AC recharged/tested/etc anywhere or should I really take it to the dealer? Tune up parts, dealer or autozone? Tranny flush is going to get done at the dealer that much I have read here. I think thats it ... any other advise to keep this thing running another 50-60K?

Thanks

Sean
