1997 Jeep TJ Repair Question
Mileage: No information provided.
1997 Jeep TJ low power on the freeway
1997 Jeep TJ 4 cyl Four Wheel Drive Manual 165000 miles
i have a 97 jeep with the 4cly and when im on the freeway it is hard to get up to 70-75 and when ever i go up a smalll hill or go over an over pass i can not maintain speed, if im going 70 i will slow down to about 63-65 and if by chance i am doing 75 then i slow down to about 60. i had the cat checked and that was fine but they found a very small crack in the header. i have checked the plug gap, wires, and cap and rotor and air filter and replace them all. where should i think about checking next? people thell me that its just because its a 4 cly jeep but other people that have 4cly jeeps say that they dont have this problem!

See My Profile,

Answering is just one of my hobbies, I am not paid like the certified guys here.
I just try to help and try to stay within my boundries.
My answer may not help much, but here it is anyway!
I do not know your Rig.
1) Have you located 2nd and Higher gears----Try shifting into them!
2) 165000 Miles may tell some of the story--things wear in your engine.
3) Tire Size---stock?.......Wide---Big doesn't help.
4) Have you got a repair manual?....Fuel Economy means Efficency!......They are discussed within.
5) Additives such as Oil stabilizer might "Slicken" the engine up
6) Weght----We will let you hash that out with him/her/other!........I have my Standards, and You have yours.
7) Timing????????? No mention!
8) Vacuum Lines / gaskets and related gizmos broke/worn/deteriorated causing vacuum leaks?
9) Injector Cleaner?
10) You may be able to find a "Performance Chip" for your rig---Maybe....Try 4WD Hardware and Others for this item....if your rig will accept one.......Remember Imma CJ Feller
