Re: 2004 Tahoe 5.3 weird idle

Thanks for all the input. I finally cleaned the TB today. Very cruddy inside. I thought for sure that would fix it. I would say it helped. The idle doesnt fall off as much as before. It does still have a noticeable drop in RPM at idle. It feels like a little shake in the seat. Until I can go get some AC plugs, should I unhook the battery to reset the computer? Does the ECM have a memory of the way it was running. I'll post pics tonight of the TB.
