I have to say that i agree that a aging car can give out a lot off expenses specially now that the major parts may need to be changed. Why dont you take your car to AAA service guys and ask their opinion.
did you get the solution to this issue. once my sister had the same thing she just got the tank cleaned and it started working again. she spent 50 aed in sharjah hope that you problem is solved too
