I don't know how much air pressure you are running in your tires, but I solved a similar problem by reducing the air pressure from 35 psi to around 28 psi. I have slightly larger than stock tires.
Since you drive only on good roads, the less pressure probably will not hurt handling and might help reduce the bounce.
Let them down to 28 psi (use a good gauge) and see if the problem goes away. If for some reason you want more tire pressure, you can then raise it a little at a time until you find the problem coming back.

I'm curious. Have you noticed any drop in gas mileage since you reduced your tire pressure?

I can't really say. The tires are 30" compared to the 28-1/2's that were on it new.
I noticed the tendency to bounce right after I got them. I figured with bigger tires, I could get by with a little bigger foot print. It would soften the ride a little, not get me in trouble with wear, and would tend to reduce bounce. So, I really don't know how much mileage was affected by the reduced pressure. Remember also, the bigger tire size changed my odometer by about 5%, making it look like my mileage went down.
I keep good gas mileage records. Correcting for the odometer error, I get about 14.2 mpg with all town driving.
Tire wear is even and the bounce went away.

Thanks, WD! I agree - the bounce issue would likely be a higher priority.

I have an 1988 yj with a 2.5 when starting and running gas shoots up and out of the side port inside of the throttle body .What would cause this? It shoots up about 6 inches or more. Any help would be great thanks.

Update- It happened to my wife yesterday. She was driving along and hit a man-hole cover...just the regular ones you see on the highway or back road. The Jeep immediately started vibrating, steering wheel shaking, front end vibrating as well as the front tires. It only lasts about 2 or 3 seconds. Naturally she let off the gas right away and after 2 or 3 seconds the Jeep returned to "normal."
We cannot recreate the problem at will. It does not happen every time we hit a bump.
One would think that if something was disconnected etc. that it would happen more frequently. I have a feeling that if I take it to the dealer they will not be able to recreate the problem and I will pay a service charge for nothing. I guess that is what I will have to do though. At least it will be on record in case something more serious happens. I just wish I could find the problem myself. Could something be lose or disconnected and still only effect it on once and a while? The jeep is stock and I do not know what type of suspension component would effect it the way it has I would agree that it could have been the brakes but this happens when we are not under braking. I was hoping that someone has had this problem and could tell me what the problem was. Thanks for your time.
#1351 of 1886 Wrangler high idle at start up

My 2002 jeep wrangler idles at about 1500 at start up for about twenty seconds. Then it slows to normal idle speed. It has just started doing this. Any ideas. Thanks, JIM
#1352 of 1886 2000 4Liter 6, low oil pressure.
Sep 04, 2008 (8:51 pm)
Mine drops from 40 to 20 or as low as 10 psi after it warms up. I have had it in to Jeep to repace the oil pump and check the main bearing clearance. The chaeked and said my oil pressure really does go that low. I have 10W 30 in it now. Several differenct shops including another Jeep say don't worry about it, but I don't want it to sieze up when I'm in the booneys!
QUESTION: Has anyone actually had one of these fixed? Jeep garage says a new engine.

My car is at the dealers right now. They tell me my problem is severely warped rotors and metal to metal brakes. As I said in other posts the dealership replaced the rotors a couple of weeks after I bought it because they had a "bad batch." How could they go so quickly? I hope they don't try to charge me for this. My jeep only has 16,000 mi. on it. Surely they do not go bad every 16,000 mi. What do you folks think?
Not under warranty....364.00 out the door. I hope this does not happen every 16,000 mi.

I have a 2006 Unlimited, and had the rotors go bad at 7,000mi. The dealer fixed them no charge (like I was going to pay), and now at 12,000mi they're going bad again. Unfortunately I'd be happy with your 16,000mi. .
