Okay I know this may have been covered a few times, but my case is a little different so I made a new thread.

-I stored my FC in the garage for 4 days and couldn't resist taking it out for a drive again. Before I let it sit for that small amount of time it ran perfectly. Idle was at 850 rpm when warm and the needle wouldn't move from there. Now I started the car up and let it warm up and once it did I took it to a parking lot that I like taking pictures at. Once i was done I started my car and it idled fine for 20 sec or so then started to sputter between 850-400 rpm, then it died.
-I checked my two vacuum lines that usually were the problem to this behavior and they were connected and fine. I have a boost guage and my vacuum pressure was fine too.
-Now I am stumped as to what the problem is
Could water have gotten into the gas over 4 days or what??? Please help me!!

noone? come on, i love my car to death and if its not running perfectly + i cant find the problem i start having problems

 

i would probably start by cleaning and adjusting the BAC.

 

really.. not much is gonna happen in four days that could cause that problem. will it even run?

 

Yeah it runs 100% perfect when im moving...i took it to redline on the highway and everything....just doesnt want to idle right. =/

 

vacuum related then.. idk what 4 days could cause tho that wasnt already there.
