Liberty '02 won't run over 25mph by arr828

It just happened tonight and I am in panic mode. Can't go to work tomorrow, if I can't drive on the highway! =( And I don't think I can with my jeep crawling a mere 25mph.
 
My axles have been recently changed, and so was my radiator because it had a leak. I've been running on these new parts for a couple of months now and no problems until today. I read somewhere here that they had issues only when the weather was warmer and smooth sailing during the colder months? But I've had this Jeep for a year now and got it right around this time when the weather's pretty crazy (cold then hot). I seriously wonder if it even has anything to do with me missing a gear! HELP please? I'm scared to drive it because I feel like the engine's dying on me or seomething and I might do some serious damage by pushing it.
 
Thanks in advance!

Can you give a little more detail? What does the engine sound like when this is happening? Are you losing electrical power? When you say "missing a gear," do you mean your transmission is not working? Are you getting visible exhaust from the back end? Are you hearing any strange noises?

Hi, thanks for your reply tidester.
When I try to press on the gas to make it go faster, it sounds like it's revving and then the sounds dies down and it's like the engine's just too tired to do anything else but run on 25mph. Going up a slight uphill slope is a crawl, makes me feel like I will back up anytime so I don't push it and just run on the crawl that it's giving me. Most of the places I called around adviced for the jeep to be towed, if we're bringing it to a shop. I have no idea whatsoever where cars are involved so pardon my inefficiency in giving you specifics. Anyother strange noise, I don't hear anything and noticed no visible exhaust, maybe I wasn't paying attention that much to my back end. I was just holding my breath til the engine died and thank goodness it did not and I got home. ='(

There are several possibilities. Your clutch may be slipping, your ECU (electronic control unit) may be faulty, your fuel pump may not be working properly and so on.
 
Perhaps another Liberty owner has had similar experiences. Anyone?

Thank you so much again, tidester.
 
But is it safe to rule out the transmission? I'm scared of that part. A couple of months ago, we had to replace the axles then they found a leak on the radiator and a patch won't do the trick so we bought a new radiator too. And all these happened just 2 months ago. The $$$s just keep rolling out our household.
I hope someone who's had the same problem could shed light to this.
 
Thanks again!

I wouldn't rule out problems with the transmission. Can you explain what you meant by "missing a gear?"

I meant it won't shift from first to second. But if we manually put on second gear, it runs up to around 45mph. Except it kind of locks.. Like it stops and moves again? As if having hiccups. It's driving us insane. And the mechanic has yet to get back to us re: the computer side of everything as he already ruled out the transmission. Said that if it were the transmission, we would have problems with the first gear and Reverse, which didn't really give us problems until we put the car manually on the 2nd gear instead of just on the regular "Drive".
 
Is it safe to reset things by removing the negative on the battery and re-attaching it again after 5 mins? Somebody suggested this.

I don't think disconnecting the battery would cause any problems unless you have a security system installed which may require some additional procedures to reset.

You can verify whether the speedometer is reporting the speed accurately by using the mileposts along a highway. For example, driving at 60 mph, it should take exactly one minute to travel one mile. A significant departure from that indicates the speedometer is inaccurate.
