Assuming this is a w124 from the early nineties, the engine bay wiring loom and the wiring of the ETA must be suspect. If the MAF has been replaced, then the short section of loom leading to it may have crumbled internally with handling - this is easy and cheap to check and if necessary fix. However replacing the loom and ETA is neither cheap nor especially easy.
