So I'm getting my 325I prepared to be tuned and worked on and I want to check everything I can, IE, gaskets, pipes, etc. Thing is, I don't know what to check to prepare for that, or what are the best things to replace before pushing some power into her.
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...
