Catalytic converter died at 15K miles. At 20K, the thing started having serious trouble starting after a heavy rainstorm.
Instrument panel frequently wigs out, speedometer and tachometer die, only to wake up again with a slap on the dash.
Gas gauge never shows tank full, and gas light comes on when there is still a half tank.
Both rear window ties broke off at less than 10K miles.
Had to replace all four tires at 35K miles.
I love driving this car, esp. on the rare off-road trips. but I would never buy another jeep or Chrysler product again.
It is interesting to hear your fuel gauge woes. I, too own a '98 Wrangler with the trusty ol' 4.0 and ran into a situation where the the gauge read a half tank and yet it was drained dry. I must say it is not an enjoyable experience to push a Jeep 200 yards prior to heading to work on a Monday morning. Additionally, the engine bogs every time I start it... I have to let it warm up for a good 5-10 minutes (even if it's already warmed up and I just shut it off for 10 minutes). Other than that... not many issues to speak of.
I have had my 98 Wrangler for over 2 years, and have made MAJOR modifications to it, and have never had one problem. I just bored out the air intake, and added 30 horse power to it. This is a must for all owners, cost $150.00 but well worth it.
As for the gages in your dash freaking out, sounds like the wiring in the dash is crossed and shorting out, this might be also causing the fuel gage to only show 1/2 full. Check with the dealership for this short or another fuel gage.
As for the tires, they only last 30,000 miles under warranty; this is any tires; even the 50,000 tires.
Yes, to the guy that stated had his air intake bored out, can you also write a comment on the other things you have done, I'm going to have my air intake bored out and looking for more modifications.
I Really Never Saw A WRANGLER witha 1.5 Liter engine, where did you get some thing like that???
