Alright so ive had my 2005 infiniti G35 coupe for about a year and it has had no problems until now. The car is completely stock and had 65k miles on it. Whats happening is that sometimes i will be drivign at any speeds 25-45 mph and out of nowhere the rpms drop to 0 and the car starts bogging and i cant accelerate and the slip light comes on as well as the traction control light. Then the cars rpms go back to normal after a few seconds and i can acceplerate again. However sometimes the rpms wont go back to normal and i need to pull over and it takes me about 2 minutes to start the car up again. Please help me!

 

Try cleaning your MAF.

Worst case scenario is your throttle body.

 

alright thanks man, and if it were my throttle body, is that expensive to replace?

 

Something similar to this scenario happened to me yesterday--except no lights came on.

I hope this doesn't happen while I am trying to merge into traffic!

 

Slip light and traction control warning seem to be sensor related. I would reset ECU first or better yet go to autoparts store and have them read any error codes to help you determine what might be telling the ECU to cut power.
