Even though the Jimmy has 217K miles I think it has a few thousand more left. We had problems with it not starting and I had local mechanic replace the fuel pump. After about two months (and maybe 300 miles) later, I noticed the Jimmy was using an excessive amount (>10mpg) of fuel and smoking a little bit of greyish smoke.
A friend told me I may have a injector stuck. I use Lucas Fuel Injector Cleaner and thought maybe putting some of that in would fix it but it didn't help.
have the same problem?
