Mercedes - car stalls


Expert: Robert - 11/1/2009

Question
I have a 1991 Mercedes 300e 2.6, the car stars ok, then when idle pressure goes to "0", when accelerate or run the car goes all the way up, temperature ok, after 15- 20 minutes in traffic, engine stalls, will start and run while in "Park", will stall when I change to "Drive".

Answer
Feliciano,
Idle pressure 'O' ????
Goes all the way up????

You need to determine if this is a fuel deliver or and electrical problem.

Start with a fuel injector cleaner. Techron Black Bottle in a tank of gas.
How many miles on this vehicle.
It is possible that your catalytic converter is clogged. Does the vehicle have any smoke  or a foul rotten egg odor from the exhaust.
If the converter is clogged then you cause back pressure that could cause this problem.
Let me know OK.
Rob
