Towed for the first time,have problem! ! ! HELP
well yesterday i towed for the first time with my 97 350 dually psd automatic. mind you it is all stock, and i was towing about 11k. It towed great all until i was about to merge onto the highway, and it has done this twice before on open roads. It seems like in third gear as i am under full load trying to merge, at about 2800 rpms or so the truck must like defuel or something, it slowly misses.. almost like a limiter or something..
any ideas on what it might be?
if i let off and it shifts, it is fine but it is almost like it struggles to get to like 75mph..
any info would be great..
is the wastegeate spring weak?
