06 c230 cold start issue
after replacing:
plugs and coils
mass airflow sensor
alternator and battery
power steering pump
radiator
now whenever starting cold it coughs and sputters and dies, unless i can catch it and hold throttle at about 4k for about 30-45 seconds then it runns fine after warming a bit.
I saw in a forum that the coolant sensor might cause this so I changed that to no avail.
does it have cold start injector? Not sure
Thanks for any advice.
