My 1992 Jeep Wrangler has a difficult time sustaining speeds above 55mph. Why? on 1992 Jeep Wrangler

While on the highway, i can get to 55 mph with no problem, but it seems like it has not power to get and maintain at 65mph. I usually have to downshift.
How can i get it to have more power and drive it at 70mph with out any issues?

Simple anwser is to take it to reliable shop that can diagnose and repair your car. It could be several differant thangs that can cause that problem you discribe. I could only guess at least 10 different things to check and test.
I took it to a reputable mechanic. He found some issue with distributor cap, and cables. Also something to do with timing.
$650 ran better as it does not loose speed as drastic but still loose power.
Have you called the shop or taken it back to that shop and told them that it still has a problem? It may have needed some obvious past due mainteneance things and that was part of the problem but not all. Who knows they could have made a mistake and need to recheck their repairs.
No, not yet
As my name say, I am jeep rookie or should i say car rookie.
What can you advice me so that I can go in there talking like I at least know a little bit.?
What are things they should have reviewed?
Simple thing to say is its running better but I still have a problem. Will you please take a another look at my car? They cannot help you if they don't know your are having a problem. If they are truly repuatable they will get to the bottom of your problem.
See if they will go on a test drive with you , so you can explain and show them exactly what you are experiencing. It may be normal for a 4cyl. jeep with a 5 speed manual trans. But unless they can actually experience what your talking about no one will really be able to say. Let us know what happens.
