Ive received so much valuable advice.This problem might be from both advised repairs needing looked at.The problem it is having is that it will run fine,maybe a little hard,and out of the blue the RPM gauge will shoot down to zero(there is kinda thump or surge just before it does this).I can usually continue to drive and of course once the car is shut off and restarted the RPM gauge is back to normal.Ive been advised this would be the result of a bad crank sensor(crank shaft sensor same thing?)Ok then the other problem it has is at lower speed,usually stopping,starting,or turning a corner it has been shutting off.Doesnt do this alot,but more frequently.Ive been told by a few,including billboast this could be a vacuum line thing and that all vacuum lines should be checked.Today both of these problems converged at the same time,had the surge,rpms shot down to zero,proceeded to stop light,as it turned green and i started to turn,car cut off.Had hard time steering to stop as i guess the power steering stops when car shuts off like that.Once stopped i crank it starts right up and no more problem for the few miles home.Is this two seperate problems?
