hey guys been a while, still havin those rough cold starts code popped up the other day and gave me a P0116, i already replaced the coolant temp sensor (the blue two prong on top of the thermostat housing). the wires looked kinda iffy going into the sensor so i did a homejob splice replacement. still no change. i had the guy at autozone clear the code but the starts still a problem. any insight?

i'm still working on this problem for my c230k

it sounds like it wants to stall on start up....like you gott heavy cam in your c class....

If you haven't done you normal troubleshooting

Check and clean the MAF
Check your Fuel Pressure
etc etc

i'm going to try another fuel injector treatment...i'm gonna get seafoam another try...if not 44k or somthing harsher

+1 I agree on tha MAF and fuel pressure. ;) You might need to bring it in to a shop that got the ability to reset your fuel pressure to factory spec.
