jlinde Posted October 14, 2012 Report Share Posted October 14, 2012 After 4 years of problems with cutout or miss at around 4000 rpm the problem disappeared after changing the crank sensors. That was nearly the last things that could be changed except cam sensor and knock sensor. No PCM error code at all pointing in this direction. I have changed and tested everything else like fuel pump, filter, pressure regulator, PCM, TPS and MAP together with a new ignition module and cables and ignition coils. The reason for waiting with changing the crank sensors was that it seemed like very tricky job but it was not when I started: I simply removed oil filter and its adapter and then it was very easy. I am writing this to just tell people that the early PCMs are limited in diagnosing some faults. Jan Linderholm. Link to comment Share on other sites More sharing options...
