Van is well maintained. Wife was driving car with 800 lbs cargo, following me in UHaul truck from Tucson to St George, UT. After 3 hours, running 65-75, wife called me and asked to slow down to 65-75 as engine was struggling. Stopped at 4 hours for gas, van was "tapping" at idle, like a stick had gotten into fan belt, or a loose part. Noise stopped soon as off idle, accelerated fine. 3 hours later, no more noise, running fine at 65 mph. 2 days later picked up UHaul trailer to drive to Salt Lake City. After 30 miles at 70 mph, saw smoke behind van, stopped and so did smoke, but tapping noise returned. Canceled trip, returned home with no trouble. Wife drove to store next day, and reported tapping sound at slow speed in parking lot. We are 600 miles from our great Toyota repair folks, and know no one in St George. Any idea what this might be? Oil level is still full.
have the same problem?
