Q: I purchased a Canadian version of the Wrangler, a 1998 "TJ." It has Daytime Running Lights on all the time that I'd like to disable, eh? Is there a way to do so easily and without damaging the system? Thanks!
A: There is a square headlight daytime module usually mounted on the firewall under the hood in front of the passenger seat I believe...... unplug it for normal operation..... Ed
Drive Train / Driveline Making Noise Not applicable Not applicable
Q: When shifting to reverse, there is often alot of gear grinding (and, yes, I am pushing in the clutch!) This happens with the vehicle at a dead stop. (I bet it'd be louder going faster!)
The clutch seems to work okay at speeds, and I don't think I have room on it to have it engage more, because I don't want to burn it out. Thanks!
A: Have you tried putting it in 2nd and then shifting in all one motion from 2nd to reverse????......... Ed
I will be trying to replace my stablizer rod link on both sides in the front of my Jeep.
When I take the part off, will the jeep fall to one side?
It seems if I have someone hold the one side being worked on up for a few minutes, I can change it right.
Will the shocks naturally sway to the other side when held up on the opposite side?
A: If you raise the truck and securely block up under the frame, so the wheels hang down....
It should be an easy unbolt and change rubber bushings job... Ed
Exhaust System Other Happens always Not applicable
Q: My exhaust manifold in my jeep has 3 cracks in it, and it's making a loud noise, along with the fact that it is using alot of gas.
Can you help me?
A: The cracks are letting noise out and fresh air in as well. This fresh unburned air makes the oxygen sensor think that the engine is not getting enough fuel, so the computer increases the fuel injector pulse width. Ed
Electrical / Lighting Systems Chugging When driving Always
Q: Check Engine light - Code 24 TPS Voltage High or low. I have hesitation on acceleration and at some speeds. Checked out resistance of TPS and could not find any dead spots. Do not know what the voltage reading should be at idle, mid or WOT. Can anyone provide this information so that I can measure it? Also, the two pins to measure? (I believe B and C but I am not sure. This is for a 4.0L TJ)
A: This sounds like the TPS would be the problem.....
Most TPS units are approx .5 of a volt at idle to approx 4.5V at wide open....
You are just checking resistance, which is one side of the equation....
Turn the ignition switch ON, and keep the engine OFF, for the voltage test...... Ed
Q: My 97 jeep wranger is missing sometimes when I drive it. It sometimes reeks of gas especially after I fill it up. And once on the highway it just stop taking fuel and was just coasting. I kept pushing the excellerator until it finally excepted fuel again. I took it to the dealership and I was told that my exhaust manifold was cracked and I need a new fuel pump. I wanted to have the work done elsewhere because of their cost so the dealership told me that the fuel tank sending unit was under recall and they would replace it, so they did. Then when I went to purchase the fuel pump, I was told that it is sold only with the fuel tank sending unit attached. Could my problems have been the sending unit or should I change out the pump? I hate to have someone drop the tank to change that pump if it is not needed. Also, if the exhaust manifold is cracked what signs, if any, would I notice from this? And how can I tell if it is really cracked? There is also a sort of raddling noise underneath the jeep when I accelerate. It has 87K miles on it and I had to replace the catalytic converter at 70K - just fyi.
A: There should be a distinctively loud noise. You will know if this is the problem, it makes a loud "hissing" noise.
Q: After taking my jeep to the dealership to find out why it is missing and reeking of gas, etc., they left my air filter open. It was making a muffled noise when I picked it up. Then a few days later it was having trouble staying running when I started it. And the check engine light came on. I found the air filter open and I closed it back up. The muffled sound was gone but the check engine light is still on. How do I get the light to go off - or can/or should I? Could the light have come on due to the filter problem?
A: Disconnect the battery positive terminal for a couple of minutes. That shold take care of the problem.
Q: My '95 Wrangler, 4 cyl, 2.5L stalls intermittently. I want to replace the fuel filter but cannot locate it. A local Jeep dealer told me it's an in-line filter but I can't see it.
Can you help me locate this filter? Thanks for any info you can provide.
A: The Filter should be under the vehicle not far from the fuel tank. But, my guess would be to clean the idle air control motor and channel that it fits in. Ed
Electrical / Lighting Systems Tuning Not applicable Not applicable
Q: At some times I get ok radio reception, other times I get nothing at all. (I just purchased this 1995 Jeep Wrangler)
My last car had before had perfect reception. Could it be the antennea or maybe the reciever?
A: My guess would be the antenna but please understand that the antenna is also connected INTO and is part of the radio.......
My advice is to go the Clarion w/CD unit... a few hundred and it works very well...... Ed
Electrical / Lighting Systems Malfunction Happens always Always
Q: Brake and indicator (red) lights will not go on. I have checked the fuses under the hood and under the dash and all fuses are OK. What should I look for next, I have no wiring diagram and wondered where the cables run in case there is a break in the circuit.
Q: My muffler blew up and I replaced it a month ago. It blew up again and I had it replaced. The mechanic said the Jeep was running really rich so the excess fuel was burning off in the muffler and baking it till it split. I can smell fuel after I turn off the Jeep. What would be the cause of the Engine running rich and how can I repair it?
A: Leaky injectors...... fuel pressure regulator out of range.... you need a fuel pressure test done for a start.. Ed
Electrical / Lighting Systems Malfunction Happens always Always
Q: My headlights both went out at the sametime. The fuse appears OK and the switch appears OK. When I turn the lights on, the parking lights come on, but no headlights. The brights don't work either. The headlights don't appear to be burnt out. What's the problem?
A: Maybe a wiring harness, BUT change BOTH headlights anyway. I had a similar problem with a 91 Ford Ranger
There was a knocking coming from my Jeep engine, so I had an oil change done at Wal-Mart. Instead of adding 4 quarts, they added 4.5 quarts.
As I went back home, there was a really strange crunching coming out from the engine.
The engine stopped running, and now I canīt even start the car anymore.
What could this be, is the engine damaged?
A: Sounds a lot like it.
The extra 1/2 quart will not have had an effect on it, but it does sound like you have an engine problem.... Ed
Q: Starts really weak. The voltage reads low like around 7 and then jumps to 14 (vise versa). I know the starter is good because I just replaced it a month ago and it is not clicking but turning the way it is supposed to but very weakly. The battery was brand new last march from interstate Battery. I believe it is the altenator but I want to make sure before I buy one.
A: does this voltage change just running or while starting? If the change is while running you may have Alt problems, if while starting that is starter, or battery problem.
Q: When I start my jeep the idle is fine, but when I drive my jeep then push in the clutch it almost dies. When this happens I notice the check engine light will come on while excelurating through 3rd and 4th gears
A: Simple though it may seem , is the gas cap on tight ? The fuel system in our newer cars relys on that cap to be on and tight . Only other thing that comes to mind is either a vacuum problem , or the MAP sensor could be at fault . It would not hurt to check the O2 sensor and do a fault diagnostic of the computers' error codes .
When the clutch is disengaged , engine load all but disappears . The engine is not keeping up with this new demand . A sensor , or engine vacuum is not telling the computer what it needs to know to maintain engine operation .
Drive Train / Driveline Malfunction When driving Always
Q: The Jeep seems to be stuck in four wheel drive even though the transfer case shifter in set in two wheel drive. I can hear the front drive shaft turning while I drive.
A: Unless you have manual hubs, the driveshafts will turn, but not inside the transfer case, until you shift into 4x4.
Then the power gets transferred through the transfer case.... Now the engine drives the drive shafts, instead of the turning front wheels turning the shafts ....
Q: Jeep starts, but it has trouble when starting. When cold outside, Jeep idles at around 500 and dies after 3-4 minutes of idling.
Doesn't begin to become "normal" until after 25 minutes of driving around (ie. warming-up).
Even then, the cold makes it hard for the jeep to keep up the idle.
A: Check and clean the idle air control motor and channel. Ed
Q: Is my front drive shaft suppost to turn while I have it in 2 wheel drive?
Today the 4x4 light didn't turn off for a few miles, so I stopped and noticed the front shaft was still turning in 4x2.
A: This is not usually the norm....
However.... an old trick with the 4x4 systems is to disengage the 4 wheel drive and then back the truck up for 10 or 15 feet.....
That helps to disengage the transfer case.....Ed
