I have an old 4 cyl. 1996 Chevy Corsica. The mechanic that I always go to said that I need new fuel injectors. The cost would be anywhere from $400 to $600. He said it wasn't a big problem now but eventually I will have to get them replaced. Needless to say, I am not looking forward to paying this money. Is this something a reasonably handy person can do on his own? I have done things like replaced water pumps, alternators, and starter motors. But this sounds like a much tougher job. Would I need any special tools or diagnostic equipment? What do you think? Can I do this job on my own? Thanks, Pete
