CEL problem

**ber55ber55** · 07-19-2006, 02:22 PM

Okay so the CEL comes on about 10 seconds in idle or when rolling down hill. But if I turn my a/c on, it goes away for a while, and then comes back after a while of driving.

idle reg valve?
throttle position sensor?
already replaced 02 and intake manifold gasket.....
also checked over engine for vaccum leak.....
please help.....

You need to perform the stomp test. Do you own a Bentley manual. If not go to www.bmwe34.net. It shows how to perform the test and there is a ton of other useful information.

Just remove the Bulb for the check engine light, early m20's like mine don't have one fitted.

common though! just remove the bulb? that is so mickey mouse!!!! what about when i do smog! the fact that the light would go on if it had the bulb will still make me fail, right?

Reboot the car using shogun's procedure. (Search archives)
If it still throws the CEL light, read the codes using either
1. the throttle stomp,
2. a Peake code reader,
3. or have your indy read it using his.
You could even try to meet up w a forum member close by with a code reader.

i have the bav auto code reader.....and it just says its lambda

the stomp test: i did it, it worked, but i didnt see any damn codes...the check engine light just flashed a bunch...where do the codes appear.

isnt there a adapter or something for a laptop to plug into the car and some software.....i did it on my friends mit. 3000 vr-4

couldnt find shoguns post about reseting and then i kinda gave up on it

the peake code reader is like the bavauto one right?

indy? que?

Do you own a Bentley? Did you go to www.bmwe34.net? When the check engine light is blinking, that is the code. After the first initial blinks, if it blinks once/twice/twice/once, your code would be 1221(that is an example). The Bentley has the listed codes, as does e34.net.

shogun's reset procedure:

Make sure you have your radio code before you disconnect the battery.

Indy = independent (non stealer) shop
