Alright this had happen to my G35 last week where my check engine light, SLIP, and VDC light came on. So I noticed that when I accelerate my engine tries to cut off on me while on the freeway. We think it is the O2 sensor but then again we don't know that for sure. Everything is replace and brand new except the battery(which will be replace soon) alternator, starter, sparks plugs etc, etc.

HELP ANYONE......MECHANIC OR NOT.........AT LEAST SOME ANSWER WOULD BE GREAT.

 

Do you have a CEL? It's most likely one of your camshaft position sensors, but without a CEL, you won't know which one. It'll eventually throw a code, but if you don't wanna wait you can just replace both.

pull codes and see whats going on.

 

I guess common sense isn't so common anymore. OP always have the car scanned for codes whenever the check engine light comes on, that'll take 90% of the guesswork out of the repair process.

 

Thank you very much we found out it was the camshaft sensors and that will be replace this weekend along with my rotors also.
