Hi
I have been looking after my C124 E220 1992 for 5 years and I have done a lot of work on her. She has a problem with a very lumpy engine at less than 2500rpm.
The following have been checked:
No OBD1 error codes on pin 6, (she has the new silicon harness)
Runs perfectly when cold up to 65deg, throttle body is moving the as it should to maintain nice tick over
After 60deg tick over becomes lumpy and poor power until suddenly at 2500rpm it runs ok, maybe a little down on power
Plugs new and all look good
No sign of a inlet manifold leek
Any thoughts as to my next move?
Thanks
Geoff
