Engine trouble 95' wrangler

[justicedogue]

Hello everyone, I sure hope you can give me some opinions. I have a 95' jeep wrangler and it has several issues right now. My engine light comes on. The guy at the shop said that the diagnostic was my O2 sensor, he didnt find anything wrong but soon after he reset it the light came on again. I also have problems with it acting like it is running out of gas but it isn't. The shop changed my gas filter, I added an additive for water in the tank but that didnt work. one of my friends thinks it could be spark plugs, or wires, or distributor cap. Anyone know what it could be and if my friend is right? I am a woman and not to short change myself, I don't know anything really about engines. I do however know where the oil light is LOL
Thanks,
Tracey

Pull your spark plugs and check to make sure they aren't fouled/dead. Pull your distributor cap and make sure the points are still good. Change your O2 sensor if the shop told you it was out.

If the diagnostic says the O2 is bad, change the O2 sensor. Water in the tank, poor tuning, etc could cause the O2 to pickup bad readings. Change the O2 first, so you rule it out as the problem. Then investigate the plugs, wires, distributor. If your 95 has never had new plugs and wires, it may be time.
These are all things that any boyfriend worth a salt should be able to do for you. If not, dump him. I think currupt is still single.

Red........that's TOO funny!!! :rofl: :rofl: :rofl:

And, justicedogue, yes...bad 02 sensors will cause all kinds of grief. When mine went bad on my TJ, gas mileage dropped drastically and power was non-existant. Good place to start. You're lookin' at around $50 (generic) or around $90-$100 for OEM. That's just the parts. Pretty easy install.

Tracy,

I would start with the basics; before changing the O2 sensor, have your boyfirend (or Corrupt, for that matter! LOL) get your plugs our and check them. Plugs are about $2 a piece, so they are cheap to replace if they are the problem (dont bother with the premium stuff; the basic ones work just fine on Jeeps!).

After that, like corrupt said, check the rotor and cap and make sure they are OK.

I am prety sure that you yourself could change the spark lugs, wires, rotors and cap, as they are simple to change, so dont be afraid to try it... You can get a Chilton or Haynes manual anywere parts are sold, and if you cannot find them, I can try to get you the Jeep Field Service Manual for the 94 (which is basically the same thing as the 95!) free of charge (I can send it via yousendit.com because the file is long; send me a PM if you are interested).

Now, if all the above are OK, then go for the O2 sensor. This is also something you can do yourself. It is as simple as unplugging the connector and unscrewing the sensor from your exhaust (should be on the driver side after the manifold goes into a single pipe) and then reversing the 2 steps to put in the new one.

If THAT does not correct your problem, you could be having the same problem I had on my '94; in my case, when the weather was hot outside, the Jeep would start fine, but then it would just quit (as if I had turn the ignition off) and then start again after a while, but it would not let me even maintain speed. This one turned out to be the fuel pump, and that is a little bit more involved given that the pump is inside the gas tank (so you have to take out the skidplate, drop the tank, take out the tank assembly, and replace the pump). The only reason I would not recommend you to do this is because the tank is heavy and it is a pain to put back in, but it is not complicated either. Anyway, start with the other options and go from simple to expensive to avoid throwing money around unnecessarily (besides, with gas being what it is, you will probably need it just to drive around!).

Hope this helps!
