random missfire
 

Gentlemen. I have had a random misfire on my 93 500 SEL which I am now thinking is a electrical short somewhere. I have gone through the Fuel injectors as it acts just like a fouled injector. I replaced the injectors and seals. It seemed to help but the miss is still occurs. I checked the plug wires and they are OK. It replicates a plugged injector or acts like a car that has a bad alternator and has used the battery but will still operate. I have looked and looked at the ground attachments and cannot find any loose connections.
Any thoughts? let me know if you have any idea where to look. PS when it runs properly it runs really well. Thanks PAUL

Checked for vacuum leaks?
