I'll try to keep this short.

Bought an 04 G35 coupe recently, 118, 000 km on the odo.

First I noticed earlier this morning that the car was idling quite low (250 RPM). She starts up fine sits at 1000 on cold start but after 5-10 minutes of driving idles at 250. The low idle doesn't have any sputter or engine shake as far as I can tell.

Next I was driving her today when all of a sudden I lost power steering. Pulled her over, turned her off. then turned her back on, she fought to turn on again but eventually got there after 2-3 seconds. when she was on I noticed that the slip light, check engine soon light, and VDC light were all on. drove home with no issue parked in my drive left her for 10 minutes then started her again and only the check engine light remained. about half an hour later the check engine light was gone and the car was starting fine, despite still have a low idle (200-250 RPM).

The Mechanic ran diagnostics on her and said both the knock sensor and cam sensor signals popped up.

has anyone run into somthing like this, or any advice.

I'm supposed to have a decently long haul trip tomorrow. Will she be able to hold out?

 

Sounds like an issue for the dealer. Could be timing.
