Hello,
Having come to a W124 200TE, from a heavily electronically managed Vauxhall Omega 2.0 16 Valve, which had numerous sensors, catalyst, coil pack etc etc, to a Bosch KE Jetronic, non catalyst Mercedes estate, it's nice to know that sometimes the most drastic of faults, are the simplest to resolve.
For a couple of months now, the Mercedes has been reluctant to idle properly when being restarted after a short rest, this had made for slightly jerky progress, though things quickly resolved themselves when a little more throttle was applied and the car cleared itself up.
The other night, around 19:30, I decided to take the dog for a walk at a local open area. It had just started to rain, that really fine rain that soaks you through and gets into everything.
Anyway, I started off and arrived without hitch, though there was some slight hesitation on a roundabout.
After 15 minutes, I bundled the dog into the car and tried to start the engine. Nothing, just turning over without catching. I floored the throttle and tried again. She started but was misfiring on 1, nearly two cylinders. I set off and had to endure very jerky progress, though the misfire cleared at harder throttle.
The point of annoyance came when she cut out at a junction and was hard to restart.
I limped home (with the running improving all the time) and put the car away for the evening.
The next day I ordered up a cap, HT lead set, rotor arm and fuel filter.
Today, I fitted all the above. The old rotor arm had a good couple of mm work away from the tip. The genuine Bosch cap had an extra cover thing over the cap, which the old one lacked.
The leads had metal ends, something the old ones lacked.
After fitting all the above, the car started and ran beautifully. I stopped, started after five minutes, everything was fine.
Fitted the fuel filter and went for a spin. No problems at all, far smoother and no worries.
It's nice to know in this day and age of increasingly complex cars, that (by modern standards) relatively simple cars such as the Mercedes and my XJ40, can be fixed easily and quickly, and in this case, with just a phillips screwdriver (to remove the cap)!!.
A HT lead change on my old Omega 2.5 V6 took me around 4 hours to complete as you have to pretty much dismantle the top half of the engine. The whole change on the W124 took just under ten minutes!.
