1900 miles. Working on this for a friend, it's his wife's sled. She doesn't do barrel rolls or jumping or anything, sled is in really good condition. When you start it, it runs fine for a little while then starts popping. I don't know if this is 'limp mode' because I'm not familiar with this era of sleds.PTO side plug is really carboned up but dry - MAG side is wet with fuel. Took carbs out and cleaned them. I did not mess with any setting screws. Put them back in does the same thing. Unplug the TPSand the sled runs fine. Made a harness and checked the return voltage coming out of TPS with throttle wide open. 4.29vdc. Adjusted it to4.0vdc. Still pops unless you unplug TPS. Pulled water temp sensor,let it come up to room temperature and it's resistance is within 100ohms of what it should be. Pulled thermostat out - took two times of bringing water up to 120F for it to finally react. Tested the coolant bottle, it failed holding 12 lbs of pressure. Swapped the cap with the one on my 05 RMK (same part #) and it passes. Checked for continuity between water temp sensor ground and TPS ground, yes.Checked for continuity between water temp sensor ground and where it and the TPS share a ground wire on the plug in to the CDI. Intermittent, if you wiggle the pigtail it comes and goes. Cleaned that connector up (had green crap in it) and now it holds continuity. Still will not run without popping unless the TPS is unplugged. I will test the TPS again tomorrow to see if it held the 4vdc adjustment. Still working on bleeding it as well. Had to add about a quart of coolant after running it today.
