C280 idle problem

5200 Views 5 Replies 6 Participants Last post by  mikhail.abraham
I have a 1996 C 280 with idle problem.
When engine starts, idle goes all the way down and engine stops.
I restart engine and hope for the best. Sometimes, I need to restart engine a few times before idle stabilizes and then I can leave.

Car stops when you put the brakes at a stop . On the highway there is no problem.
The problem occurs when I start the engine and when I brake .
I already changed the OVP relay but the problem is still there.

What is the procedure to raise the idle in the C280?:confused:
Good question!

I wasn't aware that there was a 'procedure'.

I was under the impression that this was done by the engine computer in conjunction with signals from the mass airflow sensor.
