#1855 of 1886 Vibration and Excessive Engine Noise by whataguy11727

May 23, 2011 (1:01 pm)

After replacing the clutch on my 2005 Jeep Wrangler 4.0L with manual transmission a vibration and excessive "bassy" engine noise developed. The vehicle is still under an extended warranty. The dealer replaced the transfer case but the "symptoms" are still prevalent. Any ideas?

I have a 1998 TJ Sport 4.0 and have been frustrated with a ticking noise I get in the warmer months. It almost sounds like the ol card in the spokes ticking with some loss of power. In the winter time I never hear it, but now that it is June and warming up, it is starting to act up. I have no idea what could be making this. Sounds like it is coming from the rear part of the engine and the cat, can't really pinpoint it, any help on this would be greatly appreciated.

Do you have any codes? The noise may be an overheated cat due to an O2 sensor problem.

#1858 of 1886 1997 Jeep 4.0L won't turn over by iansc

The fuel gauge has been broken for a while and yesterday I ran the tank dry. Today when I was driving (with a full tank) the engine starting losing power and my oil pressure dropped. I pulled into a parking lot in time for it to stall. The engine sounded like it was making every step in starting but wouldn't turn over and catch. I checked all the fluids and they looked good. No leaks under the Jeep. After letting it cool off for a about 10 minutes it cranked up and I fed it some gas for a minute before driving to the store. Has started twice since then fine but oil pressure won't go over 20 unless I'm accelerating hard.
 
Please help.

Actually it sounds like it's turning over, or cranking, just fine and that firing up and running under it's own power was the issue.
 
I'd guess the problem with the engine losing power and stalling is related to the fuel pump, which lives in the fuel tank and relies on being submerged in fuel for cooling.
Already fourteen years old if it's the original pump, it would have been heavily stressed when you ran out of gas. People who run the tank nearly empty on a regular basis usually experience a dramatically reduced pump life.
 
I suggest that you replace the pump module, which also contains the fuel gauge sender (I doubt the gauge itself is actually broken) and kill two birds with one stone.
 
When you engine was stalling through lack of gas it would have been turning slower and slower. Among other things, oil pressure is related to engine speed, so as the speed dropped so would the pressure.
 
At idle it would be acceptable for your oil pressure to be as low as 5-10psi, and with the engine warm at highway speeds 40psi would be reasonable.

mac24,
 
Thanks for the write-up. I've been putting off dropping the tank and fixing the fuel gauge sensor but your right, I might as well get both fixed. Now I just need to find a couple hundred bucks.
 
Will respond when I fix it.

#1863 of 1886 engine dies after 30min highway driving by pastorbeenz

My '97 SE 4banger sputters after about 30min of driving. It seems to only happen when the engine gets to about 210 degrees. Engine dies ten starts bck up but each time i have to drive slower and slower to keep the thing running. I have replaced the Camshaft pos sensor, Crank pos sensor, both O2 sensors, ignition coil, distributor cap and rotor. plugs and wires are all new. Computer spits out O2 sensor code but I replaced that twice thinking one may be defective. starting to think it may be the onboard computer... please tell me I'm wrong.

this is probably not the problem, but i've had 2 similar experiences with my '98...
 
the first was linked to the fuel pump/filter inside the tank... i'd drive for 20 to 30 minutes, it would begin to splutter and pop, rock and roll... and then eventually stop altogether... after a whle, it would restart and i'd continue on. i found, that on the bottom of my tank, there is an extruded circle on the rear right bottom corner... i'd thump that, and it would run again for a while...
 
the second problem was an O2 sensor... the diagnostic computer would read correct, however, the wrangler wouldn't run worth a dime... i had it in and out of the garage a half dozen times when i was turned onto the local jeep "guru"... he fixed the problem, said sometimes the o2 sensor would read correctly, but still be malfunctioning, he described a manual test for it, but me not being a mechanic, didn't understand... or really care, i just wanted it to run.
 
it hasn't missed a lick since...
 
good luck!
