I'm going to order a 4.0L throttle body from a used parts dealer on the internet for my 91 YJ w / 5 speed manual tranny. While researching the various used parts sights on the net some of them specify that the throttle bodies came off vehicles with auto tranny's. Is there any difference in the throttle cable linkages? Or are they interchangable, thanks in advance for any help you can provide. Can't wait to get the 4.0L throttle body and get it installed, my YJ has oversized tires that have sucked ALL the power from the little 2.5L. I have many upgrades planned and look forward to sharing them here.
