325i - Engine surges at idle
 

I have an '88 325i and when I am sitting at an idle in gear or in park the engine surges from about 500 rpm to 800 and I'm not sure which sensor is causing the issue, or if I just have a vacuum leak.

Anyone have any suggestions as to where I should check or how to find out what's wrong?

Thanks in advance.

try checking out your idle control valve.

Also check for rips or tears on the intake bellows leading into your throttle body.

Yup that'll do it.

check the O2 sensor on the exhaust pipe. I had this problem in a m20 motored e34

it wouldnt have that problem if it had a V8
haha jk

:throwrock

:orangesle this is how i drove with the stock bmw
now i drive like this with an american v8 sticken through the hood :drive2

^^^ lol, i know. me too ;)

thats is a unique mod. i dont think you have ever posted pics?

i dont kno how to

If you can, resize to be as small as possible so anyone can see. Then when you post use the *go advanced* button to the right under the post message box and upload attachments

It's a built in feature of UB not to allow pics of "hybrid" BMWs (J/K)

haha im trying to edit a signature but the pic doesnt show up, im not a computer wiz so somebody need to help me

bit late, but in yopur sig page you should be able to do [img]theurltoyourimagesyoualreadyhaveposted[/img]

there is html code for it (<img="site">) but.. dont think this site allows that

anyway, yeah :P
