Rebuilt engine, 26k miles. Stumped on this one. Engine pulses acceleration after warm up. Won't idel. This all started when I tried to clean throttle body and had removed; but reinstalled the linkage for throttle and stop sets for idle up. Tried to replace MAP sensor; but no luck. I think it has someting to do with the idle up sensor and/or MAP sensor. No "check engine" light comes on. Tried to adjust throttle positioner and idle set RPM's but still won't idle. Pulses up rpm's and then down. When I unplug the MAP sensor it will idle rough but will stop pulsing. Can someone help with this problem. I'm stumped.
have the same problem?
