A4 Stalling

A4 Stalling
Hey anyones help would be great here. I have a 99 1.8t and yesterday it started stalling while it was idle. The car will just shut off. What's weird is that the RPMs will go down to almost no power, surge up, and than balance itself out. Sometimes while driving, it may stutter like its not getting any gas or anything. What you should know is that the car just came out the shop about 3 weeks ago for a transmission overhaul. It had been sitting in the shop for about 6 months before I got enough money to fix the thing. I am just a student. Anyway I thought it could be bad gas, so I added some Fuel Injector cleaner and some additives to take out any water when I filled up. It helped a little bit, it didn't stop as much anymore, but sometimes while idle just sitting in park the RPM's jump around. Today I was able to get to work fine without the car stalling, but when I parked and just let it run, the RPM's jumped around a bit and the car turned itself off. If anyone has any idea why this might be happeing please let me know. Thanks

Gasoline grows an algae-like goo so it sitting for six months with no startups will totally foul stuff up. Like BRRMAN said, change the fuel filter, it is probably full of the crap, then see if that helps. Then do plugs, that is definitely step two. And then o2 sensors.
And definitely run some trustworthy cleaner through your fuel system.
Usually it will mess up your fuel gauge too. Has your gauge been saying full... no empty... no wait...

I am experiencing this same issue with my 2001 A4 2.8 Quattro. I was told that I might need an engine overhaul. I too put the additives in the gas tank. Not a lot of help. My CEL light was on solid for three days, then suddenly went off. I thought the same as you did with the "just a case of bad gas", but this morning, the CEL came back on, and it started acting silly again.
My question, how many miles do you have on your A4, and how tough is it to replace the fuel filter? Isn't it under the gas tank?

definately check the things already stated but when you mentioned you had transmission work done i thought of fluid levels. do you have a manual transmission? i think if the clutch is not getting enough hydraulic fluid, stalling could occur.

I changed the spark plugs, that didn't do much of anything. But I'm thinking it might be a Throttle Body Issue. When it came back from the shop the battery was completely dead. But what is weird is that it worked fine for 3 weeks. Is there any instructions around on how to clean a throttle body?

Someone let me know if this sounds logical. Does anyone think since the problem started suddenly, that it could be the ICM. Is the ICM known to just suddenly stop working?
