I was coming from Lagrange to Columbus when I was driving about 65 mph,as I was driving, the truck was stalling and started to slow down, it went to about 50 then I shifted down to fourth, went back to fifth, and it started gaining speed again. I sloweddown to 60, it stalled again, but only briefly, then went back up. About 20 min. Later same thing. What could this be?
sounds like an EGR malfunction...disassemble and examine...clean with bra-kleen and put it together with a new gasket~
Chris, My truck is an automatic, but this was happening to me as well. ... Sounds like a loss of Compression... Have a compression test done for your Head Gaskets. Cost me about $450.00 but the problem was solved. Hope this not your case and maybe an easier fix? Good Luck to you and let us know what you find.
