1996 mercedes c280 dies when put in drive


Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Not Ready for Smog test


it is not how many miles but the type of driving.

here is a OBD2 drive cycle test.

Generic OBD II "Drive Cycle" Most OBD II ("On-Board Diagnostics II") diagnostic monitors will run at some time during normal operation of the vehicle.
However, to satisy all of the different Trip enable criteria and run all of the OBD II diagnostic monitors, the vehicle must be driven under a variety of conditions. The following drive cycle will (theoretically) allow all monitors to run on (??) vehicle. (Note: Drive cycle specifics vary by vehicle!)
  1. Ensure that the fuel tank is between 1/4 and 3/4 full.
  2. Start cold (below 86°F /30°C) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes).
  3. Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes.
  4. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.
  5. Restart and accelerate to 40-55 MPH at 25% throttle and maintain speed for two minutes.
  6. Decelerate with using the brake [or the clutch!] by coasting down to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.

I have a 96 Camaro V-8, lately i the morning after


it seems like a problem that would come from two parts one it could be a bad EGR valve and once car starts to warm up it does not work but Im more towards the intake air control valve this is what keeps your engine idle controlled by the car computer if it does not operate consistent to what computer says then it will shut off,this is located next to the throttle cable on the intake plenum,looks like a large bolt with an electrical plug on the end.try removing it and cleaning it with carb. clean, hope this helps you.
