Hello,
i just bought a 1995 c280 with 92,000 miles.Plenty of service history and truely a 1 owner car since i had the original title

Ran perfect when i bought it on sunday..

Now when you start it cold it idles and 400 or so and wants to die.Will die if you touch the pedal...Once the car warms up after a few mins its fine and runs/drives fine too and idles around 550 rpm or so.Temp around 80 or so

What could it be??
Has brand new Harness...Complete one
plugs,wires,oil change,Cleaned MAF

No check engine light

 

Anyone??
