Hi everyone.
I found this stock 1991 4.0 XJ Limited with an automatic transmission for a reasonable price but the owner says it gets 11.5-13 mpg city. What with fuel prices over here in europe being 2x-3x what they are in America, I won't buy it unless I can improve the mileage significantly (17-19 mpg or more city average, preferably).
So I did some research & found this article: http://www.4wheeloffroad.com/brandpages/jeep/131_0403_jeep_xj_cherokee_mileage/index.html
Maybe some of you have seen the article before and I was wondering what your experience with these kinds of mods are. I thought I'd check with you guys who have experience with this car before investing in one.
So basically, do the following mods do any good for the gas mileage & how much of an increase should I expect for a 4.0 XJ that gets 11.5-13 mpg? :
Bored-out throttle body
Throttle-body spacer
Air intake and filter
MAP (manifold absolute pressure) adjuster
Turbo City bolt-on exhaust
Performance Distributors Firepower Ignition kit
Here's links to the stores mentioned in the article...

Also I know to keep the tire pressure right, make the car a bit lighter & drive conservatively.
So can you guys recommend anything else to get better fuel mileage?
Thanks for the help, in advance.
