Default Car jerks and shake when accelerating. Check Engine Light on...please help.

I have an 04 A4 with 85k miles on it. Never had a problem with it. Today, while driving home, car starts shaking vigorously when stepping on the gas, and check engine light appears. When in neutral, its fine. At idle, there is a few jerks. I pulled over and checked out the engine, but didnt see anything. Got back in and drove another 2 miles home slowly. Luckily I made it home.

Does anyone had a similar issue? I'm thinking its time for a tuneup. I'm at school and work all day so don't have time to do much research. Someone help with any advice on what it could be before I take it in the shop please!

Thanks in advance.

I would say a coil-pack or MAF.

First of while the car is running unplug the wire to the MAF, if nothing changes then thats OK.

Next remove the engine cover and unplug one of the coil-pack leads and see if anything changes, if nothing does when you remove one then theres you problem.

You must unplug it and reconnect it one at a time to find which one is knackered.

If your in the UK the main dealer tends to be the cheapest for coil-packs at around 30 each
