95 E320 Idle Studders Check eng lite on???
 

:) I own a 95 E320 Coupe with 100K miles.

So far, I changed the head gasket, main electrical harness, mass air sensor, sparks, wires, cables, main fan belt, cat converter, air and fuel filter...

:mad: Check engine light is on, the idle studders if in drive or park, I had the car stall on me in the middle of the road and not want to start. There are times I would stop at an atm, walk back to the car and not be able to start it... :rolleyes:

I was told by a generic pc these codes: egr and isc.

What should I do next? Should I change EGR valve or could it be a vacuum clog? ISC needs a new M16 motor? P.S. no traction control option on this car, unfortunately.

You can go get codes at other module and also check the EGR [ there was a change Campaigne on this part for your chassis], but the first thing to do is... next time it wont start , tap the OverVoltage Relay a few light taps and try to start ..
If it starts right up, pull the relay and see if it is original [ Siemens manufacturer ] .. if it is , upgrade to the newer part #
