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! |
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?

I have to get me one of those k&n intakes...

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

It took me less than 30 minutes, and I ran into some trouble along the way. Here is a writeup. Very helpful. http://www.jeepforum.com/forum/f11/i...-4-0l-1224714/ |

Would anyone happen to know where to find the thread? Like what would that be under?
