91 XJ started life as 2 wheel drive automatic tranny. Recently installed 2000 engine with nv3550, rubi tcase, dana 44 front nine inch rear. Auto tcc is still intact and connected. Bypassed nss at the harness using the connector off of aw4. Engine runs fine cold (open loop) but when it gets up to temp (closed loop) it has a miss/stutter through out the rpm range. Suspect iac or a temp related sensor. Any thought suggestions. I have located a 91 mt computer and will pick it up when funds become available.iratefla
