Re: Car stops accelerating at 5,100 rpm, 70-100 mph and freezes there when I floor it
Had the same problem after NAPA CPS was installed. Mine quit at 4600. Put in a new BOSCH CPS and problem solved. There is a thread here detailing all the folks who have had a problem with aftermarket CPS.
Found mine on Ebay at a reasonable price. Easy to install --- Google the install procedure.
