I own a 1996 Mazda Protégé with 128,000 miles with about 5000 miles usuage per year, in town driving. Mechanic diagnosed the problem as an engine intake boot split. He repaired it temporarily and said the part was hard to find. The sound went away I found the part almost instantly being available on the internet for about 25 dollars. He also said that I should junk the car. It runs fine but has cosmetic issues. The mechanic is a local respected business.
I cannot afford another vehicle right now and so junking it is not an option. Is he right? Any other thoughts?
