Hello, I have repaired more than 30000 vehicles in my career and I habit to ask you questions past I am not there in person to build up facts, data, or to exam your vehicle. I may ask you to pretense scrutiny in my stead. If study is needed and you would rather not take effect testing, I can find the money for my best advice, Fuel pressure?
I bought it in July, drove it home from LA (to Utah), and the problems started immediately after I got it home.Any new assist you can manage to pay for is appreciated. I don't know what else to attain but tolerate it support to the dealer. I know I've got the shop foreman committed on it at the dealer, but I still setting its pushed to the support as its archaic and everyone loses in this situation.
