I believe I have a faulty neutral safety switch. The car starts only in N position, It does not start in P. The car stalls at the signal lights when reducing speed/deaccelerating or while taking a U turn.Could this be because of the safety switch.I recently changed the fuel accumulator to solve this stalling problem and had no problem for a couple of months till the NSS gave way and after that I have this problem again.
Could someone please tell me whether it will go away once I replace the NSS.
Thanks
KK
