So I have an 02 tundra unlimited 4.7L and for the past three months I’ve had a rough idle but it comes and goes it idles at 700rpm then drops to 500rpm sometimes lower. After doing some research I cleaned my throttle body then subsequently I cleaned and regreased the fly by wire motor then I cleaned my MAF which someone in another discussion recommended and still no major change. In my last attempt I changed both my TPS and MAF and it still has the issue. I plan on changing my spark plugs next week and putting seafoam in my gas to see if that helps. My truck hasn’t thrown a code at all and my mechanic checked for misfire codes and nothing he said he couldn’t help me so if anyone has any advice or has had the same issue I’d appreciate the info
