Hey all!
I'm having a hard time diagnosing a problem with my car. I've got misfire codes on cylinders two and eight. I've changed spark plugs and coils, and just changed my fuel filter. Codes are still there. The car idles kind of rough sometimes, runs beautifully when accelerating between 1500 - 5000 rpm, but as soon as I accelerate over that mark the CEL flashes and I lose practically all power. The rpms keep spinning but the car will not accelerate anymore. After changing the fuel filter it seemed to alleviate some of the issues. Car runs a bit smoother and starts up better than ever, but the acceleration issue is still the same.
Next step is fuel pump. I'm just wondering if anyone has advice or experience with this. Any other places I should look or any relatively cheap possible fixes before I pony up the cost to take it to the dealer?
Any advice is greatly appreciated!

Welcome to VWAF

What are the codes?

P0171 bank 1 lean fuel supply. P0300, P0306, P0308.
Cracked or damaged lines seems to be a go to but since it runs well everywhere short of 5000 rpm I don't think that's it. It has to be a fuel pump, or could I be off here?
