2004 1/2 Diesel Dodge PU,SRW,6sp.LB,Quad cab: traveling down the freeway and acceleration became reduced and then back to normal and then consistently reduced and pulled over and had Chrysler tow it to Vancouver, WA. Dodge dealership. Advised that it was a failed lift pump and covered by warranty to be retrofitted to inside the fuel tank. When they punched in my vin# they told me that there was a "partial restriction on the powertrain" and they didn't know anything further about it or what specifically it meant for my truck. Has anyone heard of this designation or know how to get specific info about what it refers to? Thanks,Dithlev
