I am still trying to tackle my 200 miles to 17.5 gallons (when i fill up usually) i cleaned the egr, maf, iac, seafoamed it, changed the plugs and nothing at all as far as an increase in fuel mileage. before i start spending money on o2 sensors and wires and whatever else i want to just take the intake manifold off and see whats going on underneath. If i have a common fuel leak, where is the leak most commly leaking from? I know that the spider and fpr seem to be parts that fail over time, how much is the part to fix a leaking spider system or what part is it? Does the fpr on these cars go bad and cause bad gas mileage? Im hoping to take the intake off tomarow or monday and see if im leaking fuel anywhere then go from there, so if anyone can give me any pointers or pics of what to expect if i am leaking fuel that would be great.- Thanks- Jason
