A couple weeks ago my 87 cherokee would stall if i took a bumpy road or took it out to the desert. It would run fine, but if i wanted to yeild or stop, it would just shut off on me. So, I took it in and got new relays in it and a new cap with a bunch of wires they told me that it needed(dont know what its called), and I also replaced the fuel filter....for three weeks it was running good, i took it out to the desert same things i used it for...until yesterday i was coming back home, and i hit a bumpy road. then it stalled on me, some one suggested me that i could be the computer too....but I just wanna know what else can it be??? Anyone know??
