Hey guys, I just created my account today :clap: so don't rag on me yet. Haha.

I purchased a 2004 325i 5 speed with 145,000 miles. It is the smoothest thing I've ever drove! But that's not the point.

In low rmps, it jerks and hesitates very slightly.
It is most notable in 3rd gear around 2,500 to 3,000 rpms.

I just filled it with 93 oct. and put some Lucas Fuel Treatment in my tank, and it seems like it's working at the moment.

I've eliminated the possiblity of the trans. giving out.

I don't know if the fuel system is just clogged or something worse :censor:

Any input would be appreciated!

At you're mileage a likely culprit are the VANOS seals. Do a search on that as well as beisan systems (I believe that's the correct spelling) for more info. Your problem sounds like it could be that.
