I have a 5 speed 4 cylinder head 1993 jeep wrangler yj. Beautiful car. Now, I know the 4 cylinder isn’t that fast, however I should be able to get it into 4th gear. I usually get to 3300 rpm’s in third, however when I shift to 4th it drops immediately and can’t get back up. Def a speed problem because I can get to 2500 rpm’s in fourth going down a steep hill near my house.

I’ve been trying to fix this problem forever, and want to try quick solutions before I rebuild the carburetor

Here’s everything I’ve done to attempt to fix the problem.
Coil, spark plugs & distributor cap have been replaced
Fuel lines are all good, tires are also good.
0 vacuum/fuel leaks
Cat delete

Any help would be appreciated

I recently installed some new drivers using terminal, however now it won’t find Ethernet cable or any internet options….it makes absolutely zero sense to me. I’ve been trying to fix it for hours, and actually tried switching back to windows before that also didn’t work..had that shitty missing drivers issue. Any advice?
