engine code p0301 please help

[joeyponz]

so my audi when i reach around 2,000-2500 rpms hesitates and starts to shake. it said misfire cylinder 1 and i changed all 4 coil packs and changed the spark plug for cylinder 1 yeah i know i had to change all 4 but wanted to see if 1 would do anything. anyways problem is still not fixed does anyone know what it can be?

I have a p0302 cel, which is a cylinder 2 misfire and I've scoured the interwebz which said that it may also be injectors...take a look here: http://www.autocodes.com/p0301_audi.html

Thank you changing the rest of the spark plugs now and if that doesnt work imma just bring it to a shop maybe because i work mon-fri so dont have much time to play around with it and my car is completely stock. I changed the fuel injectors recently and 02 sensors and engine mounts as well.

I'm in the same boat. I would love to work on my car but work has me strapped with no time. I'll have to buy parts and bring it to a shop. I need to fix this p0302 cel and this damn exhaust issue. 🏻

Given that you've already replaced the coils and plugs, probably either a bad fuel injector and/or carbon buildup.

I just replaced the coils and plugs and it works good now but the ce light is stil on

You will probably need to clear it, did you try that?

[joeyponz]

No not yet im not sure how to do that

I had similar issues and people told me it could be the wiring harness to the coil pack. If you feel like stripping all the plastic off and following the wires to take a look go for it.
