97 intermittent issue
Not mine but my nieghbors and thought I would do some research for him. As stated it's a 97 with 180k on the clock. Manual trans, 4x4.
What's going on is the truck will run fine, then all of a sudden bog down and start clattering like there is air getting in the fuel, pull off the side of the road and shut the truck down. Wait for a couple of minutes then fire it up and it's all good again.
Last year he pulled a 5th wheel 170 miles one way with no issue. On his return trip the truck acted up 5 times, all within 20 miles of each other.
It is setting a check engine light but we don't know what it is yet.
