Hello,
My 89 300e 3.0 with ~130k miles on it just started what I call stumbling--not stalling or dying--just missing a beat or two after the engine has warmed up and although it's most noticeable at idle I suspect it's happening at other times too. It's not just misfiring though. It feels like its not getting any spark to all the plugs for maybe half a second every 5 to 10 seconds and it has definitely gotten worse in the last
10 days.Maybe water in the gas and I'm going to dump some drier in with the next tank to see if that helps and am also considering a new coil but I thought I'd put it to the group first to see if anyone had any ideas about what else to check. I have new plugs and wires, distributor cap and rotor, one of two fuel pumps and new fuel filter, and also a new EHA valve so I think I can safely eliminate those as culprits.
Any suggestions about what to check next would be greatly appreciated.
Best regards,
Mike
