I own a 96 328i with 172k.

Everything was running fine and I put some regular gas in it by accident and noticed a loss of power. I figured no big deal because I only put in 20$ of regular so I just filled up with premium and put some fuel system cleaner in it. A few days later I notice alot of power loss when floored but at kick down its still fast as it was before. a few days later I begin to hear a ticking noise from the back of the engine (towards the windshield) at idle. It seems when I give it some gas and it gets to like 3000rpm it goes away. mabey the sound of the engine is drowning it out?? anyway the car seems to be running better and is getting back to its usual peppy self but why am I still hearing this ticking noise. I've noticed since I've owned the car that sometimes i'll floor it and it will be super quick and other times it won't be as fast. What could this be?

Could be your vanos unit, how much oil do you have in it as of right now? Check the level. Is it an auto or manual? Also, not using premium will not effect your car severely unless you are shark injected.

its auto. I have the proper oil level. The oil goes over the half bar when hot. How can I tell if its my vanos unit?

this is very odd, I have been getting the same thing over the last 2 days. Its a very noticable ticking noise, and I dont know if I am mistaken, but when I also floor my car (Funny to say but its the same car) and I get to 3000rpm, I feel a little loss of power, and then once it passed that, it feels ok again.

I would think a failing vanos unit.
