My 190E ran rough so I took it to a independent garage and they said it needed a fuel distributor because one of the injectors was glogged and not getting fuel. They quoted me 900.00, I didnt let them fix it. I finally took it to another shop and all my car needed was a injector, now my car runs just fine.

How could the first shop make a simple mistake like that? And has anyone else had something like that happen to them?
