I believe the 4.2 died out in 91.  :-(I also think the 4.0 HO came in that year too.Cherokees had the basic 4.0 until then when Chrysler changed thecomputer management system and the heads and/or the exhaust.My books all say 91/92 is the big change year.Mike86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '0088 Cherokee 235 BFG AT'sWilliam Oliveri wrote:
