88-420 SEL- Rough Idle - After Injector Seals Changed
 
I just had my injector seals and holders changed in my 88 420 SEL.

When I fire the car up in the morning, there is a very rough idle till the motor reaches Temp. Then it simmer's down to a very nice idle at 1000 RPM.

What could be causing this?

You might have to adjust the mixture a bit. Not uncommon when vacuum leaks are fixed. But that is just a starting point. It could be a list of other things as well.

sounds like cold start is either malfunctioning or they may have reconected vaccuum lines wrong
