Runs for mins when cold then starts and then stalls repeatedly

With this revelation, I definitely think you could be on the right path with replacing those coils with the correct parts. It could be that the coils have incorrect resistance and/or are missing some other kind of electronic “tuning“ device such as a suppression diode. It would certainly be unusual but it’s not inconceivable that something about the ignition coil and/or the reflected voltage in the primary circuits are causing your EZL/ignition control unit to overheat and shut off. On that subject, how is your ignition control unit mounted? Is it firmly bolted onto the left side inner fender as it should be. Is there a film of heat transfer paste between it and the inner fender?

Hi Klink,
Thank you for your important input.

Yes the ezl is mounted properly with the white paste evenly distributed underneath. I may apply new paste seeing as it's from 95.

Well Duralast coils are not Bosch and I'm certainly not going to leave them in.

Clearly my crankshaft sensor is not faulty so lucky for me I can return the new one I bought.

Will order the coils from AutohausAZ as they get delivered in 48hrs to Cali from Arozona for free.

There is still a misfire but the car stays running!!

Thank God!

wow..this was a nice set og post"s to wake up too.
Awesome to see that it was ignition related,and that it stays running.awesome
hopefully for you ..you wont be paranoid forever..and ALWAYS waiting for the car to stall on you

Yes no doubt!

I am waiting for the new Bosch coils to come. I honestly feel that it will be running well after I replace them. I mean almost everything has been replaced [emoji16]

All week I had been visiting dealerships to see about getting a new car to be my daily driver.

I'm hoping that now I can finally get this e420 running reliably so that I can make it my daily car.

It was the Coils!!

I put the new Bosch coils and I put in the non resistor spark plugs and now the car is not misfiring. I drove it down the road and then I stopped at a stop sign- I thought it stalled! But it was running! Smooth as butter!!!

So anyone reading this year's from now.

If u have Autozone Duralast ignition coils remove them and throw them into the nearest garbage!

They were new on my car by the previous owner. So I thought great I've got new coils there. Bloody made me waste 3 months and hundreds of dollars on other parts!!!

Now I will continue in my journey to make this my daily driver.

Guide rails
Ac compressor and sensors
Blower motor and resistor
Alternator regulator
All steering arms lemforder

Loads to come

I want people.to.benefit from my unique experience.

Nobody online had shared the experience I had.
I was very concerned but at the same time I realised that nobody had this issue because there must be some meddling or water interference that occurred.

So it turned put that the Duralast ignition coils had LOWERED the resistance in the ignition spark system and this must have been causing some overheating in the EZL ignition module. So it would shut down at approx 65 degrees Celsius EVERY single time for 3 months.

Big lesson learned.

I hope this saves you time and money in future.

Thanks to all who tried to help. Really appreciate it

Duralst next to the new Bosch coil. Duralst was noticeably shorter in length

WOW. That is crazy... I never would have expected faulty coils to cause a shutdown at a specific engine temperature, every time. Totally bizarre. Very happy to hear you finally solved the problem!!

What's up with the blower motor, AC, etc? With such low miles the VR should be ok, ditto for the steering linkages.

Hey Dave

Yes the car was parked for 5 years and leaves etc blocked the drainage so there was quite a bit of water entering in electric areas. I've cleaned all that up now.

I managed to fix the heating system yesterday.
I installed a new Resistor under the blower motor. Then found the blower was almost completely seized, so I thoroughly sprayed electric contact cleaner and then wd40 to get it spinning well. Now the blower works and I finally have heat!

I am going to replace the Air con compressor, drier, condenser, pressure switches and regas it.

Not bothered to start running into problems with the AC with my family riding in the car. I personally never use AC unless I'm wearing a suit and need to not sweat etc [emoji16]

Dave,

With regards to the steering, I like to have brand new parts to help me enjoy the tight steering, as close to new as possible. I certainly dont desire to drive any w124 that is not driving like new. But the parts are not damaged or anything. In fact I think its prob just the steering damper that needs to be changed. However, seeing as Im getting an alignment I may as well put all new Lemforder parts. FCP Euro has the best price on the set.
