Was wondering if anyone has experience with this before:
I have a 1999 Mercedes E320, 280000 kms, was cruising on the highway being a bit agressive (but not too much), then I see check engine light go on and blinking, then turns solid.
All of a sudden car starts running rough with very weak power. I couldn't drive it home and had to tow it the next morning to the repair shop.
Indie shop scans the code, said engine is misfiring, said might be spark plus but I replaced spark plugs 4 months ago. They looked into it some more and said '3 of the 4 injectors are not opening fully', looks like electrical problem. They tried to identify root cause, even tried 'another computer', but couldn't find the cause.
Indie shop recommended I send the car to the dealer since they have more 'advanced equipment' that can troubleshoot the problem.
So that's where I am right now, my appointment with the dealer is next week.
I've benefited a lot from this forum, and have been able to identify many common problems with these e320s that I've had before (rear window regulator failing, front spring rusting out), but this particular problem I'm having no one seems to have reported before.
Any ideas what's going on?
