Mein Auto: 330CI 2001
Help! I have a 2001 BMW 330Ci with engine issues. Would appreciate some feedback!

Hello! I have a 2001 BMW 330ci and when i start the car the engine chuggs and sometimes turns off. I noticed this happenening especially once it drops below 500 rpm and the engine chugs/ spurts. Also if i ram up the engine while still in park and switch to drive the engine will stop, again still a chugging bumping of the engine. Also sometimes when i drive it seems the engine wont shift gears on its own though its an automatic, I floor the gas pedal and wont go above 2000 rpm and going up hills like this is at a snails pace.. Any idea what could be the problem. THere is a brand new battery and often the car isnt used for years at a time, in which i have to buy a new battery.. Thanks in advance!

Take it to an Autozone, O`Reilly`s, etc. and have them scan the codes (most places will do this for free). Write down their findings, and post those results here.

Will do that asap, so just ask them to scan the codes and theyll know what that means? What does it mean? In the meantime if anyone has any idea what might be the causing these engine issues would be greatful!

Unfortunately without codes, any response would be a guess. And it probably wouldn't be a good one.

Codes mean error codes logged in the car computer. You should take the car for a good long drive every few weeks. Or have a friend do it if you're away. It's generally not good for cars to just sit. Did you put fuel stabilizer in the fuel?

Batteries can be preserved with trickle chargers.

I had to take it to four different places and finally the conclusion was that someone had removed the OBD2 so I wont be able to check the codes for diagnostics I know my car was totaled and had to be remade so maybe thats the cause In any case I had them take a look at the engine and they recomended this an air intake valve for a 2000 323 ci... thats the actual make of my car..... http://www.amazon.com/Genuine-135414...ds=13541435627 with a 100 dollar service charge. Im not confident this is the cause though there seems to be ducktaped wrapped around the old one im using, but they seemed to notice it right away.. Just thought Id check here before I go ahead and have them install it. Could this be the cause??

That boot is a very common spot of failure. Causes a vacuum leak and then the car runs like snot. I HIGHLY doubt your car doesn't have the OBD2. Maybe they didn't know where to look for the port, but it is there.

It`s a bit hard to believe that in this day and age, nobody can figure out your car. Where do you reside ?

+1 ^^
IIRC for that model, the obd port is under the hood and not inside the car, perhaps they looked inside the car and didn't find it
