I have a problem with my 1989 Jeep Wrangler 2.5L with 5 speed manual trans. When I first got the Jeep I drove it for a few months and didn't really notice any problems because I was only going 10-15 miles at a time. I decided to take a trip about 40-50 miles and that's when it started bogging down, stumbling and losing power. This problem got progressively worse along the trip. Now I can only go a mile or two before it starts to act up. I can shut the key off and back on and it seems to reset whatever the problem is for a short period of time. Things I have replaced are as follows...
Bypassed fuel filter to check if it was clogged
I'm thinking I need to change fuel pump, fuel filter, fuel pressure regulator but can anyone assist me on anything else that could be the problem. Very new to the Jeep world but somewhat mechanically savvy. I started with the electric items first due to being able to reset the Jeep by turning the key off then back on.
