Hi All, just started my '92 W124 up after standing for a month, battery flat, jumpstart OK. After driving long enough to warm it up, the engine started misfiring on the idle and threatening to stall but just recovering and keeping going. Also misfiring and struggling to get going from stationary. Runs at 80 OK round the by-pass but misfiring slightly on acceleration at speed.
I fitted new HT leads about 18 months ago so it may not be that. I don't know how old the distributor cap or spark plugs are. The car has done about 90,000 miles. Once upon a time I would have cleaned the carburettor then changed the spark plugs but this is fuel injection, and modern plugs are ruddy expensive. Where do I start?
