Any ideas. I have R129 1990 500SL. Always had a poor (ish) idle. But now nearly un-driveable when warmed up. Stutters and as though on few cylinders. Plugs changed (Correct non resistor champions from Green Plug company), Rotors, Dizzy caps, Dizzy insulation disks (ouch), HT Leads, New dielectric paste on EZL and second hand OVP. Its been in to Merc who "thought" it might me mixture. Tweaked t a bit and wanted 8 hours to perform more diagnostics. PS no fault code from blink reader.
I have removed coils and was going to replace them as reasonable. Fuel filter also fairly new.
I also had an issue with sporadic instrument cluster Where rev counter and some other gauges would sometimes falter. Now I understand rev counter is fed revs from MAS so I was looking to swap this out too.
Anyone got a spare MAS.. 008 545 87 32 is part number. Yorkshire ish ideally but anywhere. Buy or borrow.
The only other thing I have researched is CPS. If they crack they can cause an issue when they heat up. Anyone experienced this and are they hard to change. ? Or EHA could be playing up. Anyone know how to test ?
Any other suggestions gratefully received.
Cheers Lee
