k well i got my code reader working i think. i have a code 67 (O) i have a book and it says neutral pressure switch (NPS) circuit failure, circuit open (3.0L MAP, 3.0LMAF-SFI, 3.8L SFI) What's a NPS? what does this mean? i know i should have the engine warmed up, but i didnt have time when i did it.... if that makes a difference. it read 67, 10, 11 with koeo. shouldn't i see something for my CEL that comes on at high RPM's (but disappears when i let off) after my LT and OR x-pipe install? I havent gotten a CEL for a day or 2 because i've been driving like a pansy though.... how long does it stay in memory?
