[W126 Coupe] 560 SEC Cutting Out

[samsisic at comcast.net]

On a possibly related issue, my 88 SEC w/ 90K mi. is cutting out when cold, before it reaches normal operating temp, where it runs fine... 

My mechanic suggested replacing the injectors. He noticed that mine were original which are made of steel and tend to clog over time. 

The replacement Bosh injectors are made of brass and much improved. 

I will be replacing these soon and see if it makes a difference. 

Just a thought if you have checked all the other possibilities such as fuel pump, EZL, relay, ignition system, crank sensor, fuel filter, fuel in tank ;-)... etc.
