Default Wtf is going on with my car???

Ok last thursday I got back from work car was running great. about an hour later I went to move my car because it started to snow. when I started it up & it started idling real rough (i always had a rough idle) & and the Vsc light came on (my cel was ready on for the o2 sensor). So I disconnected the battery & all lights cleared, but it was still idling rough. For Two days i let it idle for 10 minutes & drive 5 miles, no codes no vsc light.

Yesterday I let it idle, it was rough like usual, but then the car sputtered out and died. I tried to restart & keep my foot on the gas and started and immediatly stalled. every time I tried ti started it stalled quicker everytime until it now cranks but does start. my gas was low and the temp dropped from 40 to around 5 saturday night. Could to gas froze up. I put heet in it but it just make it start, but choke. are these symptoms of the timing belt slipping??

try cleaning the injectors with fuel injector cleaner....next think about cleaning the throttle body and mass airflow sensor....then check the spark plugs...time to replace.

Timing belt? Doubtful based on what you said happened. If the timing was off, then it can cause rough idle, but the car wouldve driven like crap too. If the timing belt broke, it'll make a funny noise(s) when you try to start. Sounds like some general maintenance/tune up needs to be done.

Try cleaning or checking the Oil Control Valve.

search around, there are lots of posts with similar problems to help you find the issue - it sounds like something minor that has to be identified.

I would start with the easy cheap stuff - clean the MAF, T/B, spark plugs, maybe injector cleaner etc

Update: got my battery tested & it was only 50 cranking amps! So i got a new one & put 2 gallons of gas in the tank. After a long crank it fired up & now its running fine. Was it gas or battery?

If it does it again then it could be your ignitor going bad. When your ignitor goes bad your car starts and run fine for a while like 15-30 minutes then it chokes and dies and won't start up again. After you wait awhile you can start it back up, but then it'll die again in a shorter time, and the time get shorter and shorter until it won't start anymore.
