Strokermjcomanche Posted May 21, 2017 Share Posted May 21, 2017 I know this isn't English class and I'm not your teacher , but it's very hard to read / understand what you are saying . Proper punctuation would help out tremendously.... If you're from outside the United States I apologize as the translation may get lost in the mix ..

offthepavement Posted May 21, 2017 Author Share Posted May 21, 2017 what are your compression numbers?hiya pete hows it running ☺..ya know I'm not sure what the compression is on it right now.its at my mechanics with the brake issue cause i just don't have time or the patience to tinker with it right now.I'm going to mention the lack of power to em tomorrow if u could relay what the compression should be around,if ya know,to me i would preciate it.they don't come into shops very often Sent from my LG-V410 using Tapatalk Link to comment Share on other sites More sharing options...
87MJTIM Posted May 21, 2017 Share Posted May 21, 2017 What engine and transmission do you have? I have a 4.0 manual transmission. The axles have 3.07 ratio. My MJ does exactly what you describe. You could have the axles re-geared to 3.55 or higher Link to comment Share on other sites More sharing options...
Pete M Posted May 21, 2017 Share Posted May 21, 2017 to make power an engine needs fuel, spark and air. a hiccup in any of them can cause your issue. everything from a clogged air filter, fuel filter, cat converter or injectors. or maybe a bad fuel pump or pressure regulator. or even worn spark plugs or corrosion on the power feed for the coil. there are lots of things I would check before jumping to compression.

My MJ does exactly what you describe. You could have the axles re-geared to 3.55 or higheri also have the 3.07 ratio il6 manual.it does great until i get to a hill which are every where haha.I'm thinking fuel injector since if i give it gas before hill and then hold it and pump down every couple secs it does ok mostly as in holding speed but if its not pumped just right then naw she slowing down not drastically but by the top I'm down to 55 or 50 depending on how big hill is.the injectors look twenty years old haha time to change em Sent from my LG-V410 using Tapatalk Link to comment Share on other sites More sharing options...

Mine had the problem since it was new...30 yrs ago. Just downshift to 4 and you can get up any hill at 65 MPH. Link to comment Share on other sites More sharing options...
