I'm currently looking for an MJ. I've owned a cj, yj, & a few XJ's in the past but they all had the 6 cyl. Which I really loved, but I have found a truck that I like that has the 4 cyl.,. My question is.... was there a carb. & fuel injection model? & what are the other up's & downs of the 4 cyl? The truck I found is a 89. Thanks in advance for any help.
