rough idle
When I am at idle('99, 3.0l ,47k miles) I have an intermitent vibration/shake that runs through my truck. It will idle smooth for a bit then vibrate/shake again. I have only had this truck for about 2000 miles. Put the cheap gas in the first time and had lots of engine knock.Have run 2 tanks of 92 gas and knocking is not as bad but still there when accelerating or under load.
Any suggestions?
thanks

The 3.0 is known for pinging but normally 92-93 will stop it. The is also a TSB about it so you might be able to get it covered under the emmisions warranty. You could also try cleaning the MAF.

I can't post the TSBs but if you email me I can give you more details. I don't think the TSB will help you if it still pings on 93 octane, I would look at the MAF and other places first.
