Just bought my first jeep a few months ago. Started having an issue when cruising at any speed where the exhaust tone dramatically changes to a low tone and the rpms lock at 2000 and will not go up with acceleration. Unable to gain anymore then my current speed or lower. If I slow down I can not...

So... 8 months ago I bought an 06 Grand Cherokee 5.7 L. In October, I replaced Shift Solenoid A. Not long after bringing it home, I started having issues with stopping. It stops but lurches forward and rpms jump up and down and bottom out, sometimes dying. Only dash light that comes on is the...

How it started: took the car to the shop for a metallic sound which I suspected was from a worn out pulley bearing. Turns out it was the connection between the exhaust manifold and the exhaust pipe, the mechanic tightened it. He also loosened up a bit the accessory belt as it was a bit too...

I have a 2005 Jeep Wrangler that I have had some problems with and trying to get it all sorted. I have a reoccurring issue with my tachometer where it moves erratically. The problem has happened a few years since I bought it (3 years ago) and I usually just unhook the battery to reset it and it...

On my way home from work I realized my Jeep never shifted out of 2nd the whole way home. The problem is that it was in 2nd the whole 20 min 75 mph drive home (68 mph on speedometer, 75 because of tires). What damage could this have caused? And why did it not shift...it was fine on the way to...

I hit a lot of rough terrain in Saguaro National Park and since then the Jeep has had a loss of RPM and the RPM jump and my transmission surges when I hit bumps in the road. I've checked the grounds and just installed a crank shaft position sensor. I'm at a loss as to what to do next on it. Any...

I have been having a hard time finding a solid answer on this, and its probably one of those issues of everyone has a different opinion. I have been trying to find out why I have bad MPG and I am now at driving habits. I have a '95 ZJ 4.0 5 speed. Putting aside the issues with engine or...

I have a 1990 Jeep Cherokee Renix 5 speed, ax-15 4.5" long arm and 33's. it's the base model and everything in the engine is stock, some new parts but no upgrades. Ever since I got the Jeep stock a little over a year ago, it's had super slow acceleration. Taking me about 10 seconds to reach 60...

Hello everyone, i decided that after months of on and off research into why my Jeep doesnt go into overdrive, i would join this site in hopes of finding an answer. I have looked everywhere, and tried so many things with no luck. Here are a couple facts to take note of: 1. I had my tranny...

I have a 2004 unlimited, when driving while going a steady speed I sometimes get a push of power and accelerate even though I didn't hit the gas at all, also when I am driving and let off the gas to go brake or turn my RPMs drop to almost 0 (I have stalled twice my friend helping me diagnose the...

I recently bought a 1999 automatic Jeep Wrangler 4-cyl and while driving on the highway the RPM read around 4000-4500 going about 65-70mph. This seems high to me, but this is my first jeep. Is this normal? If not, what could be causing this?

Hey all, I have a 2.5 L 95 yj that has been giving me some idling issues the past few months. The RPMs would drop real low randomly while at a stop light. I eventually replaced the TPS and IAC valve, and that has stopped the real low RPMs (200-400 it was). I have noticed now that when stopped...

So the temperature has started to drop and I have recently developed a whining noise under the hood. It is related to the rpm's. It does it when driving and when stopped. I believe it is coming from something being run by the serpentine belt. I tried turning the steering wheel back and forth...

Iv recently got my jeep back from the jeep dealership in hopes that my problem had been fixed but yet again a couple days later its acting up again. I can drive my vehicle for roughly half hour (continuous driving) then suddenly my engine light will turn on and my rpm will go very high (at 60km...

I am having a new issue (or if it isn't new, it wasn't as noticeable previously) where I am getting a fair vibration with the engine turning at about 2200-2500 RPMs, regardless of whether or not I am moving. I have not noticed anything outside of this range, either lower or higher RPMs. I can...

when i start up my 5.2 it will idle perfectly fine if i leave it in park, if i drop it into drive it will idle for about 5 - 10 minutes before the rpms slowly drop to about 100 then it will die. if i try to start it immediately it wont crank over and the my battery gauge says my battery is...

Hello, I need some help diagnosing an issue...I havent been able to find my exact problem on here after a few hours of searching. I have a 93 jeep grand 4.0L. The other night I came home from work and my jeep was running fine, then the next morning it wouldnt start. When I try and start my jeep...

I got my first car a few months ago. It's a 99 Cherokee 2 door. It's an automatic. When I start driving (0 to x mph) the rpm go up to like 2 1/2k then shifts into second a tad abruptly at approx 25 mph. It feels like it should be shifting at around 2k. then again, it might just be me going nuts...

when im driving and hit a bump i used to get speed wobbles alone. as of lately the speed wobbles are now accompanied by my rpms dropping while my jeeps bouncing around, once the jeep is done bouncing around the rpms pick up from where they left off... what could the problem be here?

I just noticed yesterday while I was driving around, my rpm's were staying above 1000 while in neutral, or park. Or at least it would take about 5-8 seconds for it to drop below 1000, back down to the 'normal' 750-800 range. I witnessed it also jump up to close to 2000 when I would switch into...
