Life got in the way again after the post above. One of the inside rear tires leaked, I let the truck sit and by the time I got the tire good. The brakes were low on fluid. So, the truck didn’t get driven on the road. Just around my property pulling trees and being a mobile scaffolding for tree trimming. Starting and seeming to run ok but still with the chugging exhaust pulse mentioned above.
Then the world got the plague and shut down. My school is shut down, but we still work at the school taking work to the students. But, all of my off work activities have been stopped along with all of Colton’s Corps of Cadet activities. Basically, I had time to mess with the Whistler again.
Tires and brakes all good to go again. I drove to town and put in 36 gallons of fresh fuel. Then hit the open road for a 30 mile loosen it up cruise. It wouldn’t pull more than 2200 rpm and had lots of black smoke. I thought no problem and just kept the pedal down figuring a run is what it needed.
2 miles later I felt a lurch and decided a 30 mile drive might not be the brightest idea. I got turned around and headed for home. It was 90° out and the temp had gotten to 200°. Something that has never happened before in any condition. I was not able to get over 2000 rpm now either, but made it home.
No load rpm was 2300. New air and fuel filters got the no load rpm back up to 2900. But the chugging exhaust is still there. I tried doing a long drive again today. 2400 rpm on flat ground was all it would do. No lurches though. Temperature slowing climbed to almost 200 again. I backed off and held 1900 rpm for a few miles and the temperature stabilized just below 200. Something is still not right so I turned around and headed home again.
Coolant is full and not being used. Since the odd exhaust pulsing started when we did the hydraulic head and this thread discusses the troubles we had getting it even running after that work. I decided to just make this a continuation.
Any bright suggestions?
