Background info:
I am from Toronto, and its winter time, these days, the weather has hit -15 to -5 degree celcius which is frozen cold.

Intro:
My G35 is stored in an underground parking lot, its been stored for about 6 weeks now, every week or so, I would drive it around the 4 levels of the underground parking lot ot prevent any rotor rust, or battery dying, and to prevent tires from having lumps.

During the last 5 days, I haven't had time to start/warm the car and drive it around the lot because it was snowing bad and weather is like -15 degree celcius (so I am stuck at my other home).

Today, I went over to the parking lot to start the car and run it a bit. The shocking/depressing XMAS present I am receiving is the following: VDC Light and Slip both came on.

What happened:
I hop into my G35 Coupe (6speed). Start the car, it started without hesitation. It sits at 1100 rpm (cold start) then after a second, it dropped to like 0 and the car felt like it shut off, but then after a half a second, it poppped back up to 800-900 rpm (like it start on itself again). Then it sit at at that rpm and fluctuates between 700-1000 rpm once every while. I had it ran for 5 mins, then the VDC Off light and Slip light both came on. I tried to rev it, and it wouldn't go over 1500 rpm. I also put it in gear, and try to rev it, still wouldn't go over 1500 rpm. I let it warm for another 5 mins, do the same, wouldn't go over 1500-1600 rpm. So I shut off the car for a minute, turn it on again, still act the same way.

No ABS light, the CEL is on, but it was on before I stored it, I had it scanned, and it says my gas cap has issue. But I had been driving with that CEL for 3 months without problem, VDC and SLIP never came on.

So, what is the potential problem? Cold weather? Gas cap issue? Brake rotors with some rust? Frozen gas line? Frozen fluid? (HAHA) Throttle?

Anyone with similar experience in cold weather? Or similar situation? Or similar start-up issue before?

What did you do to check, and what was your resolution if your problem's fix? And what was the approx. cost?

I would think its the gas line. Try using some gas treatment (heet) and see if that works. My GF had the same problem here in wisconsin on Monday. She has a new chevy malibu and her car started just fine Monday morning. She even let the car warm up for 10 minutes before she drove the damn thing (suprising). 3 minutes later when she is about to hit the interstate the damn gas hand and rpms drop and a *shiz* load of lights came on and the car shut off. The temperature was -9 F registering -39 with wind chill. She eventually was able to get to the gas station down the street and put some heet in her gas tank. She used about 2 bottles and filled her car up with premium gas. From then she was fine. The sad thing about it was that I couldnt save her. My G was in the parking lot buried in snow, plus i have the summer tires on because i thought i was going to be out of wisconsin so I didnt buy winter tires. Anyhow try some gas treatment and see how that goes. Stay safe in that cold weather.

 

^^ I had the same issue with the VDC and SLIP lights a few weeks ago. I took it to the dealership and they had to replace the throttle body. Luckily, it was under warranty.

 

I had this after I replaced my spark plugs. I didn't completely reattach the mass air flow sensor on the top of the stock air intake. Once I finally tracked it down, and secured the mass airflow sensor, it was all good. I would recheck all the connections as well as the belt tensions. I have heard that could also be the issue. I hope it is one of the these fixes, or at least something simple. Good Luck.
