1991 300 ce
Hi,
I have a 1991 300ce w124. I replaced the E.H.A. Valve and the Idle Control Valve. The car starts, then dies. Or, it starts and sputters until it levels out and runs fine. I tried to adjust the fuel/air mixture and it helps sometimes, but after it starts several times, it defaults back to the same problem. HELP me please. a

I will help you!!!!
When my car was cold it had a very hard time staying alive.... I got it soo mechanically adjusted that it ran at 500 RPM upon startup and usually held that engine speed.... I replaced the Over Voltage Protection relay (OVP) and got all my electronic fuel functions back... (like cold start enrichment) My car now idles at about 900RPM in P, 750RPM in D and then slows to 600 RPM in P or D when warm and in gear. The part is about $70 to $75... but is a very common culprit.... Before you buy a new one... check it out... there will be a fuse on top of the device... pull it out and check if the fuse is broken! Even if the fuse looks okay, replace it anyways! Trust me on this one! See picture for location!
