Good morning!
I'm ready to start hunting-down a poor mileage condition I've been putting-up with for awhile. I went from an ordinary 17 mpg to 13 mpg. I just thought if I gave a list of what's right with it, and maybe you folks would give me some ideas/starting points:
generally runs great
it might be taking slightly more cranks to start lately . . . 'not much, if so
regular lube, oil and filter changes
plugs, rotor and cap about 14,000 miles ago
it seems to have a subtle miss at idle
everything works, this leads me to think no vacume leaks
recently passed DEQ with flying colors: THC 1.71, NOX 1.41, CO 27.2, CO2 816
no overheating issues
all original
I'll probably start with some vacume checks and maybe replace the plug wires since I don't know the history on them. Other ideas before I take it to my local Jeep shop (NOT the stealership)?
Thanks! Don
