98 sport 4.0 200k miles and has recently started losing power and sometimes stumbles on acceleration
Im about to go thru all the sensors,fuel system and change the timing chain/gear sets
what are gimmicks and what works on the 4.0
timing gears instaed of chain,pros and cons?
a milder camshaft.....which one?
Fuel pump or pressure regulator?
With my 31's I use to get 16mpg now its dropped to about 12 in the past 2 months.I checked the cat converter temps it was 263 in and 354 out so It doesnt seem clogged
I run an ax-15 on 3.07 gears until I regear to 4.56 and add 33" tires sometime this year.I dont exceed 2500 rpms,mostly shift at 2000.i run my Jeep onroad like a grandpa,offroad I ride in mud,2nd gear low,maybe 3rd.No excess skinny pedal.
bottom line im looking to awaken my sleepy engine,not looking for high performance but a couple extra ponies wouldnt hurt.
