At the dealership, we get a lot of complaints like yours and they all started with running too low on fuel or running out.


Start with replacing the fuel filter and get back to me.


Running low/out tends to suck up micro trash from the bottom of the gas tank and that gunk clogs the fuel filter.

Possible fuel filter, fuel pump issue. Check out these items and let me know what you find.
I hope this info helps!~subyguru~

takes cats off, it will run better,more power and better fuel. check eng. will remain though

Why would you bother with a dealer after the warrantee runs out ?

Never heard of the 200,000 repair shops available,with better
results & cheaper than a dealer.

You can't ask what something costs
You do not have any idea what ,if any problems you may have
