300SL MAS problem??????
I have recently purchased a 1992 300SL -24. The engine starts to go sticky and then stall after the engine been running for 1 hour or so.. I have changed and replace a new MAS unit. The same problem occurs.
However, when i stalled, i put the old MAS unit back on, the car feel crispy as new. Basically feels like MAS overheating.
Any idea what i should do???
Thank a million in advance..
