Your article about changing the 2.5L throttle body to a 4.0L (“Dethrottled,” Jan.’13) has me asking a few questions. I have a throttle body from a ’91 4.0L Cherokee with automatic Transmission that is in good shape. First of all, will it work on a ’95 2.5L Wrangler with manual Transmission ? And second, is there a way to change the idle after swapping out the 2.5L IAC and TPS to the 4.0L body? My engine in stock form idles at approximately 800 rpm but when I put the larger throttle body on it the idle jumps to approx 1,100 rpm and does not settle down any lower. I’ve driven the Jeep for several minutes to get the engine completely warmed up, but that doesn’t help lower the idle. I like the additional power it seems to have at the lower end. Drivability would be great if the engine would go back to a normal idle. Any suggestions you might have would be greatly appreciated.
