I have a 90 4.0 xj that has a really bad flat spot in the throttle. When you give it gas it hesitate,sometimes it will stall, it will also backfire a little through the throttle body. I cleaned the throttle body over the weekend and the iac. Did not make any difference. If the map sensor vacumn is unplugged, it runs perfect,but it smokes like crazy. I tried another map sensor, but this made no difference.
Any thoughts,ideas or guidance is appreciated.
Thanks
Scott
