That computer and those injectors are precisely why your truck rocks (well, them and the solid front axle).
But I imagine if you were to want less reliability, less performance and worse fuel mileage, I bet somehow you could adapt the carb from a 4.2L Wrangler. But to make that work I bet you'd also have to swap to the YJ's head and manifold. This should be relatively easy to find since YJ owners are dumping them for the better flowing and superior fuel injection setups found in your truck and later Wranglers. Heck, you might even be able to trade your stuff for some YJ owners stuff. :D
But seriously, the computer in our trucks has a long history of reliability and a proven track record of performance. It should never cause you grief. :thumbsup: :cheers:
