Default Re: Rough Idle When Warm, Dies Sometimes

A few months back, around December, I had this issue, it got so bad that it had a very hard time starting. I replaced all the upper intake gaskets, and the biggest one at the bottom (cant remember the name) was clearly not sealing anything. After replacing these the problem went away, for the most part. It starts fine most of the time but if its particularly cold it will act as if it isn't getting enough fuel. Its been showing the lean code for almost the entire time I've had the truck, about 25k miles. MAF has been completely replaced, as has the fuel filter and plugs. I'm going to try the fuel cleaner next time I fuel up and see how it goes.
