Shooting Jack The oxegen sensor will definitely make a difference in power. I just replaced mine and couldn't believe the difference in power. Still not a speed wagon but it's certainly better.

Atlanta Al I have a 94 and deal with the same power issues. At least you're in TX which is relatively flat. The mountains in North GA are killing me (or so to speak). I have 32's and just passed my emissions test so I know it is not the exhaust. Welcome to the world of having a 4 banger with large tires. I still love my jeep.

rtread On '97 and later models, the fuel level sending unit is part of the fuel pump assembly inside the gas tank. It has a history of being a problem (I have my own problems) and working on it involves removing the gas tank. There are threads on here giving details.....the SEARCH function will find them.

The four cylinder is not going to have an overabundance of power. One with that much mileage may also have problems that are keeping the performance down. If it were mine, I'd do a tune-up on it and go from there.

Welcome to Jeeps!

AvJeep okay well its the 4cyl and the tires are 31" and it has 175xxx miles.

see the fuel gauge when filled goes to the fill line then like a couple miles in the gauge seems to not read any more.

and for the power i just dont know where to start seems to have low end power but when it gets to going highway speeds it seems to not cut it

Wildkarde 2.5 four cylinder or 4.0 six cylinder? What size tires? How many miles? etc, This forum is full of really knowledgeable people, but you have to give them something to work with. But if you supply the background, i guarantee some one will give you some sound advice

97 Tj help with engine power. and fuel gauge situation

hi all.

i recently purchased a 97 wrangler tj and i have been sorting out all the problems i need fixed first problem im having is the fuel gauge reads empty and i just filled up and i dont know where to start with the fuel gauge if its even that.

second is the vehicle has some power issues. the top end speed is like 55 60 mph which is a problem on the highways here in texas. im not sure if its a fuel injection problems or maybe a clog in the hoses. it runs wells in 4th gear up to like 65 70 mph and when shifted to 5th the power goes to like 55mph and up hills it loses a bit of power. i bought a new exhaust still having problems tho and i changed the spark plugs

please any help would be nice
