Fine tuning the cherokee
I have had my xj for about 7 months now. When I bought it, it had 110500 on the ticker. Now its coming up to the 120000 mark and I wanna have it running in peak condition. So far I have done 2 oil changes, given it a seafoam run through, new spark plugs, new muffler, brakes, k&n intake, just simple stuff so far. I want to know if there is anything else i could do to have it running at peak performance. I just adjusted some throttle cables today and it is running better than before, but i wanted to see if there is anything else along those lines on making the 4.0L as good as new.
Thanks!
Thanks!

You could look into the 703 swap. Which is using (Neon) injectors with 4 ports on the injector instead of 1.
Also, how much of a difference did adjusting the throttle cables make? Worth it?

I noticed a huge difference in response and acceleration, so yes. I think it is very worth it considering it took me all of 15 seconds to do it. How hard is it to do the injector swap?

Injectors can take about 1-2 hours given that you're taking your time and have all the parts that you need. I upgraded to the ford 19s and so far have noticed a smoother idle, some more throttle response, and haven't driven it enough since especially since I took it on some trails to determine if there were any mpg gains
