This is a great topic.

Does the 3.0 have the same tendancies toward carbon buildup as the 2.6 we are talking about? I've got about 150K on the 3.0 in my 89CE and have a little bit of a rough idle. I've been putting off the injectors.

Also, can "injectors in these systems with the fuel "distributor" be cleaned? I've never had them removed and it's so drastically different than the "american" fuel injectors I'm used to.
