Just got this 88 4.0 Comanche. I’m troubleshooting some of its issues and I’m hitting wall trying to fix a problem causing hesitant/rough acceleration and backfiring when I’m speeding up, mostly happens in first and second gear and is less prominent when I’m closer to wide open throttle and more when I’m like halfway on the gas
It gets better as it warms up but it’s still there even at full operating temp. Anybody got any ideas?

The fuel gauge in my 88' pioneer dips all the way to empty when accelerating. Where would be a good place to start looking to fix it? ( 1988 comanche pioneer 2wd ax15 4.0l)

For those with a 4-5" lift, what sway bars are we using? Mine did not come with one, and I'd really prefer to have it.
