1G no start when cold and idle surge. help!!

[Talon__22]

91 talon tsi fwd. ive had idle surge only when cold for quite some time. but its starting to bug me so any help with that would be great, but my real concern is the no start when cold. this is very recent. never happened until i filled up with premium. also the car has been in storage since november. it will catch every now and then and eventually fire after about 10 min. if i give it gas it stalls untill it has been running for a couple of min. any help would be greatly appreciated.

You might want to watch the development of my post COLD START PROBLEM? EVIL CAR! I basically have the same problem. My car has not been in storage though and I am sure it is not bad gas.
GOOD LUCK!
