get out and push

That's such poor acceleration that something big is wrong. If the check engine light on, the computer has gone into limp mode due to a bad oxygen sensor. Also, you should have the catalytic converter checked - if it's failed/plugged it could cause this.

It's *slightly* possible that a failed VANOS actuator could cause poor power, but it's usually not bad enough to take away 1/2 your power/torque.

As the other responder has mentioned, if it seems like the auto transmission is slipping, the transmission may need servicing or replacing.

Can i do any of these repairs by my self? Or should i take it to a mechanic?

The problem is, you don't know what the problem is. You'd be wise to spend the $80-$100 for a mechanic with the diagnostic tools to figure out what the problem is, then go from there.

An O2 sensor and catalytic converter are easy; auto trannies and the VANOS actuators are jobs for specialists or very experienced home mechanics, which it doesn't sound like you are.

Thanks for all of your help. Im definently going to get it looked at and fix it because i know my car can run better than it is right now

One VERY simple check, how dirty is the air filter? I saw a 520i do the same thing, the air filter was ancient and letting practically no air past!

definitely go for service. specialized check-up of course. a 325 should accelerate under 10secs without a doubt. my STOCK 320i e30, not e36, does it around 9secs. but manual.
