Default 1990 300 SEL Rough idle then all good

All of the sudden when I went to start my car, it was very hard starting, then once started, it would run very rough and my ABS light would go on. Then after warming up, the light would go out and it would run like a top. It does not do this everytime, just whenever it feels like it. I had a look at it and he replaced 2 different sensors, one that was bad and one that was related to the cold start injector. It still has the same problems. This car has about 140000 miles, and has had excellent care and maintenance!

Please help, any input would be great! Thanks in advance, Ron

You need an overload protection relay, it's the relay with the red top and the ten amp fuse in it.
