bvalentino Report post Posted April 8, 2014 I just recently bought a 1997 Holiday Rambler diesel pusher and am having problems accelerating. The pedal is very hard to push / depress. Any thoughts??? It is a Cummins 325Also when i use cruise control I have plenty of acceleration. I went back to the engine compartment and checked the throttle and it had plenty of free movement and was fine. I am thinking the problem is in the accelerator pedal itself. Any thoughts would be appreciated.Burt Share this post Link to post Share on other sites
dickandlois Report post Posted April 9, 2014 Burt,Welcome to the FMCA forum ! The fact that the cable was free at the engine throttle connection and the accelerator peddle is hard to depress, sounds like you might have 2 issues in the throttle linkage. You mention the throttle cable is free at the engine, is it under spring tension that returns the cable to the idle setting freely ? Gummed up or rusty pivot points on the peddle and a gummed up throttle cable tension return spring issue on the throttle assembly. Rich. Share this post Link to post Share on other sites
hermanmullins Report post Posted April 9, 2014 Burt,Are you sure you have a throttle cable? You may have throttle worked by a rheostat that transfers a signal to the engine. It may be stuck or in a bind.Herman Share this post Link to post Share on other sites
