so i pulled codes again and i got different ones after fixing the first problem.

during KOEO test i got:
67- neutral pressure switch (NPS) circuit failure/open

and then the continous memory codes are:
41,91- HEGO sensor out of range/ always lean
and the computer read the same number twice (both 41 and 91)

and then i got the same codes as i did last time for the KOER test:
41,91-HEGO sensor voltage low/ lean
and these showed up twice too

i thought i fixed that ground cable by putting it on one of the bolts on the back of the intake. i'll redo it and try it again tomorrow. but what is the nuetral pressure switch??

thanks

check your 02 sensors or check for a vaccume leak as far as the neutral sawfety switch it might be time for a new one.
