first post rough idle when in drive

[tonic27]

hi guys, i had a new toque converter fitted about 1 month ago and since then when i put the car into drive or reverse the revs drop to about 400 and the car then stalls, this only happens on startup on a morning (seems to be when its cold outside) then when i have run the engine for about 1 min or so everything is ok.

had it down to mb no faults shown on comp,

i think it something to do with torque converter??

any ideas ??

thanks

The forums a little quite at the mo, probably all tanked up with the football

Do you have the type of car, engine, age, mileage? Any and all info will help. Could just be your idle settings need adjusting, or your glow-plugs are shot, depending on what car you have.

A few questions
1) what is the model and age of the car
2) How does it idle in P when cold?
3) When switching from P to R/D at this time, is the shift smooth or violent?
4) Is there any difference in the shift between cold (low revs) and warm?

I'm erring towards something on the cold start/ idle control side of things rather than the torque converter.

the car is a c220 cdi with 37k on the clock, the fault only occurs when the car has been stood for somtime, seems to be more when its cold outside.....

when i have got it to be ok (started the car twice) everything is ok.

starting the car on a morning is fine, its when i put it into drive that the revs drop to around 400, then when trying to turn the wheel the engine drops even further then stalls.

can i also add that this fault is not happening all the time.

thanks.
