Puttering E36 w/low power

HI all. I recently purchased a 94 E36. The car was running great until I filled the tank up and drove 20 mins. Once i got close to my destination the car started puttering, almost sounding like a light subaru exhaust. When I would press on the gas pedal, the power was lower than before. I have been doing research on here and decided to check on a couple of things.
I went through the basics. Air, Power and Fuel.
I cleaned the MAF and wiped down the interior of the intake. I found nothing unusual, no tears or holes in the lines or cracks.
Moving on I checked the plugs and wires. The plugs had some carbon build up on them and slight oil residue on the threads. I decided to change those with the plugs indicated on one of the other threads and checked with Pelican parts for order.
Last, I proceeded to do the check engine light/code check by pumping the gas pedal. It gave me a code of 11. Cam Positioning Sensor bad. So, I changed that out.
I hooked everything up, ensuring that all of the plugs were put in correctly and tight. Started the car up and I still get the same effect. I drove it down the block and it felt a little smoother, but I still have the same initial problem as when I started.
Should I proceed to attack the fuel filter/pump etc.? Should I plug in a code reader and check or clear current codes? I know this thread is probably in here somewhere, any help is greatly appreciated.

THANK YOU

Sound like a dead cylinder somewhere. I personally would try to see if all the coilpacks are in good working order first.

I had the same problem with my 325I. Mine would actually die sometimes. It ended up being a broken hose between the air intake and the idle air control valve. The IAC valve is up under the drivers side of the intake. Hard to get too.

Another thing to check are the coil packs. Disconnect one at a time, you will hear a difference is engine sound if the coil pack is good. If you do not hear a difference in engine sound when you pull a coil pack, it is probably bad.

Change out the fuel filter and run some seafoam through the fuel tank with a full tank of gas.

Just some ideas.

Make sure there is no water in the new gas and the cap is on good.

I did end up checking all of those faults you all listed. The dead cylinder seems to be the fault right now. I tested the coils and 1 of them were bad. I am now on my way to purchasing one through pelican, since no one seems to have one in stock. I will post an update as soon as I get the part. Thanks guys.

hate t state the obvious, but this occur immediately after u put that gas in? maybe you need to suck that crap out and check your fuel filter, if those other sensor problems where dated before this then they probably didnt cause it.

Sometimes they just simply expire!

i figured they just expire. The previous owner told me he grabbed some coils from a junk yard and put them in. Im guessing thats where the fault started.

Coils just die with age. That is normal.
