SOURCE: catalytic converter question 94 Jeep 4.0

Most likely yes, why remove it, it only pulls about 1-2 HP at wide open throttle.

SOURCE: catalytic converter

HI, this guide will help you with this replacement.

Step1 Lift your jeep. Unfortunately, the catalytic convertermag-glass_10x10.gif sits about midway down the length of your jeep, so lifting one end or the other will not do. Ramps are your best bet to get you within reach of the parts when working from home. Luckily, this is usually the hardest part of this repair. Step2 Be patient with the bolts, as they are often hard to remove due to size and awkward placement. You may have to drill or saw bolts to remove them. With this in mind, you should pick up new bolts, nuts and seals for your replacement project. Step3 Buy a catalytic converter specific to your jeep to avoid extra work. A generic part must be welded into the jeep, while a vehicle-specific model comes pre-welded to the proper pipes for easy bolt-on installation. Step4 Remove the 02 sensor (with an O2 wrench) before unbolting the catalytic converter. Then, you should remove the pipe connecting the sensor to the converter. Depending on your exhaust system, you may have to remove more pipes before you unbolt the converter from the muffler. Step5 Replace the old catalytic converter with a new one. This should be the easy part, as you simply bolt the new part in place. Step6 Reattach the exhaust pipesmag-glass_10x10.gif and 02 sensor, and the basic job is done. Make sure you replace any cracked or rusty pipes while you have the exhaust system apart.

  • Catalytic converters often fall under a separate emissions warranty that lasts at least 7 years and 160,000 miles. Even if your car is out of its regular warranty, but it is a newer model, ask your dealer to replace the part for you free of charge.
  • Rent the O2 wrench or socket if you do not own one. Most auto parts stores carry this tool for rentals.
  • In many states, older (vintage) cars do not need a catalytic converter, so you can gut it or remove it completely. No damage will result from running a car without a converter.
  • Due to emissions standards, it is illegal to buy or install used converters.
Please rate and god bless:)

SOURCE: 1991 jeep wrangler clutch

U have what is called a hydraulic clutch, one of the hydraulic cylinders hs failed, there is a master and a slave cylinder. The most likely and most common cylinder to fail is the slave cylinder, this requires the transmission to be pulled out to replace it. the art is around $125.00, while the trans is out u might as well replace the clutch, the labor is about the same. Here is a picture of the part, let me know if u can see it.

SOURCE: replace 1995 jeep wrangler catalytic converter

If it has flanges on both ends, just unbolt it and replace. If it has welded pipes you will need to cut it off and use adapter sleeves and clamps. Really not rocket science...at worst, you may need to remove the hangars on the rear portion of the system to get enough room to install.

SOURCE: 1991 jeep wrangler: alternator overcharging

It sounds as the voltage regulator which is built into the back of the alternator has stuck. Occaisionally this even happens on new ones. Would suggest taking the alternator back as it shoud be under warranty.

Can I interchange a 1980-1985,305 chevy engine with a 1991 305 chevy?


as it is the basic 305 block the differences may be fuel injection over carburettor which may require sensor attachments but basically the engine should just slot in place.

2000 A6 BLOWS #25 FUSE


A/C keeps blowing the fuse after I got it recharged. Its the R-12 system and it seemed to be ok before but now I got it recharged and replaced the blower motor in the front and now as soon as I turn it on it blows the fuse. I replaced the 3 fuse black and even rewired the fuses then took off the connectors tot he rotary switch and replaced those but it still blows the fuse. Any suggestions?

Could I have messed something up on installing the blower motor. __________________

We have a 1991 jeep wrangler 4.0 and we changed the fuel pump and now the coil is getting no fire when i hook the battery back up


My 1991 Wrangler would alternate between no spark and no fuel. After replacing the crank sensor, the coil, and the fuel pump twice I started chasing wires looking for a bad ground. There is a black with a yellow stripe wire that comes out of the rear body harness between the front e brake mount and the front door post(very hard to get at)right above the bottom dash edge that should be securely grounded to the front e brake mount. As soon as I secured that ground everything worked properly again.
