Engine light came on, I had my mechanic do a 120,000 mile service and diagnose the dash engine light and the intake manifold was replaced. When I picked the car up I smelled diesel. I drove it 13 miles, when I got home I smelled diesel again. I opened the hood and there was diesel all over the left engine side. There was a wet, split fuel line, leaking fluid in the parking lot, a blue plastic set small rings (like the olympic symbol) sat near the split hose. It could have caused a fire, and other cars to be in danger from slick road, among other things.
First incident in July 2011 but same ongoing issue and at the dealership at least 8 times in 11 months. Currently at the dealership again for almost 3 weeks now. Its always the same "symptoms" but always told its another problem. . . . . As follows: -sputters and jerks -exhaust or gas fumes overcome the car -engine revs but the car wont move, then jolts forward. -stalls when trying to start, it jerks violently making a putting noise as if it can't get fuel then dies. -there's a beeping noise coming from something in the engine when it stalls that no one seems to know what it is. I have replaced: -intake manifold -all fuel sensors -low pressure fuel pump -high pressure fuel pump -melted fuses with unknown cause -two batteries -other smaller items related to fuel system.
