I had a look around, wasn't able to find another source for injectors, but maybe someone else has had this problem....800 clams sucks just a bit.It's all the same issue.... and they examined the cam lobes, they are fine, they will take a very close look at the bearings when the injector comes in.
I am not one of those owners that blames every single problem on poor designs, I am sure the engineers were trying to get around a problem when they designed my car. I do, however, hate being charged 800 bucks for an injector.
I am currently chasing the glow plug recall issue. I believe my car had this recall.
