In park my Tracker surges up and down at 2000 rpms when warmed up...Then at 3000 + rpms it cuts out...Here is what I have found out by tinkering around with it...If I unplug the one of the sensors that is in the intake manifold I can get the surging at 2000 rpms to stop...Then if I unplug the Map sensor the cutting out stops at 3000 + rpms but then it will not idle right but if I plug the sensor on the intake manifold back in the idle smooths out...Then I have the surging again at 2000 rpms but not the cutting out at 3000 + rpms...What do I need to do? I have replaced both pieces with others and still the same thing...
It is probably out of water as mine did that and the radiator was dry. due to a bad water pump.
