Absolutely yes. It started immediately and smoothly after replacing the plugs, rotor, backing plate, distributor and coil. I did it all in one go so I can't say 'exactly' if one things was an issue over another but I suspect it was the coil given the sudden failure and the coil was under stress from trying to overcome the higher resistance in bad gapped plugs and old distributor.
190e Mercedes 1987: replaced spark plugs then took it for smog test. Passed smog test. 2 weeks later started shaking when on a stop. Runs smooth. Starts good. What to do?
Replace the ignition coil from the first part of the video, sounds like a bad misfire. Before spending money on new parts I'd take off the distributor cap and see what it looks like in there. May need to scrape contacts and clean it up. If it's not too bad/cleaning it doesn't help replace the ignition coil. Other thing to check would be if your Valve Cover Gasket is leaking AND the gasket around your sparkplugs is leaking too. Getting oil onto those shiny new spark plugs would cause some decent misfires. Still looking for the part number fopr those spark plug seals myself..... If none of those things are the issue I'd check what your battery is reading with the AC on full blast and the headlights on. I THINK its supposed to be around 14.5V (find another source on that).....if its fluctuating or constantly reading below that then that points to the voltage regulator or the entire alternator being bad. Voltage regulator is like 40$ and is right on the front of your alternator and is easy to replace (or so I have heard).
Thank you for this! Very helpful
Did it solve the issue?

Thank you, lately been having issues with start and running, it runs for a while then shuts off, so will give it a go.
