When i drive somewhere and leave the car for 5 minutes and try starting again, the rpms jump and then fall to below .5 and the car feels like its gonna stall, and sometimes does turn off. When its cold in the mornings i have no problems. Anyone know what this could be? 03 6spd CLS

 

I had that issue and have it again. When my 01 CLS is turned off when fully warmed up and I leave it and try 10 minutes later I have to feather the pedal to get it going. I believe last time is was a fuel pump relay.

It threw a check engine code so I am going to drop it off in the morning and will advise.

 

Most likely you have the TPS loaded up with carbon deposit. If you accelerate/step on the gas, does the car respond normal? When you let go of the gas do you get erratic idling? If you have these symptoms you may be able to clean the part and reinstall. If after removal and cleaning it, does not make better then you will need to spend about $150 for a new part.

 

Thanks alot guys ill definitely get these things checked out. And yea when i give it some gas it will stay on
