i am about to inherit a 93 ZJ 5.2 V8 AWD jeep and im wondering if there is anything i can do to get good fuel economy on it?
also the RPM gauge is a little off... at idle it goes to 0 but it goes up like normal when you drive it, is there an adjustment or a sensor to replace?
thanks for any help
Keep it tuned. Plugs, cap, rotor, wires, synthetic oil, air the tires up, dump a can of Syntec fuel systems cleaner in the tank. Other than that it's no neon so the answer is "Hahahahahahahah" ;) You could go aftermarket with exhaust and if it is the early 93 V8 with the skinny intake hood, then you could install a short spacer. Jeep increased the runner's depth in late 93 because it was restrictive.
That I have no idea.... The gauge is controlled by the ecu (computer) so it could just be a bad gauge or bent/moved needle. A Jeep dealership can hook up the test gear and run the gauge through its range.
The rest depends on how well it was maintained and how it was driven.
Oh.. and do take it to a dealership to see that all the recalls have been done. There are some critical recalls for the 93 year.
