My 2003 First gen g35 sedan died today. Here are the symptoms

- started normally

- drove normally up to and just past a stop sign down the street

- then noticed gradual slowing, then no response to accelerator, then engine gone, and no power steering. It seems like the whole panel lit up.

- I managed to restart and drive maybe 20 feet or so before above repeating

- probably 4 or 5 episodes of this before making it (barely) to stop across the street from our house

- able to restart and pull into driveway

- seems like it will restart after leaving rest for 15 mins or so

I have read about the camshaft position sensor going bad...any idea if it would be this?

Please help!

I had the same issue a few days ago, and the check engine light was on.

 

might be the camshaft or the Maf going on you.

 

Sounds like the throttle body is bad.I had the same exact responce when mine went out and im on my 3rd one.

 

I recently washed the engine bay by the way, I didn't spray it or anything I used a damp rag. My concern is that water may have dripped down on to the spark plugs from the plenum. Any other ideas?

 

Just played with it a bit more, it starts up well and immediately when I have left it for a while. It hasnt quit while just idling and revving in park.

The exhaust smells different, but it could just be because of the new HFCs.

 

Interesting! In to see what was the cause...not an issue I've heard of before

 

Cam sensors would throw a slip and vdc light, can't be that I'm thinking

 

superchargedg, good call :P

the throttle body needs to be replaced, there was also a code for a burnt O2 sensor or something, as well as a code relating to the voltage on the actual check engine light :S

They are going to replace the throttle body, do a reset, all that jazz. Then well see if any codes remain.

 

Glad it was something simple

 

Car is all better!

 

So what all was performed, just a throttle body replacement?

 

Yes they replaced the throttle body, but Im not sure that was the issue. See I was driving home and then it died again. After I called the tow truck, I opened the hood and checked everything like before, but this time I took off the engine cover (I have a 350Z engine cover so there are no vacuum hose connections hidden by the it). To my surprise, one of the bolts on the engine grounding wire was fairly loose. I am guessing that I didnt tighten it enough last time and it has slowly become looser and looser. If you get this problem, CHECK YOUR GROUNDING WIRES! I tightened it up and it was beautiful after.
