Hi. I've got a 1997 Altima that has suddenly become a problem. About three weeks ago, the service engine light came on, so I took it to the garage to have it checked. They said the code was for the mass air flow sensor. They also said there was a problem with the exhaust system. The charge for replacing the maf sensor was $600 and they wanted another $500 to fix the exhaust. I asked if having the maf sensor replaced and waiting a month or so on the exhaust system would hurt anything. They said no, so I had the maf sensor replaced but nothing was done about the exhaust. Now, three weeks later the service engine light is back on and they are saying I need a new egr valve and egr sensor. Are all of these things related? How much should I expect the egr valve and sensor replacements and work to cost? Would fixing the exhaust solve all these problems? I hope someone can help me out. I'm waiting until Monday to tell them what to do. Thanks in advance.
Buddy. most estimates are free, and if u dont feel comfortable with that
garage, then the choice is simple. Find a garage u can trust or feel
comfortable going to. Just like the dentist.
