Hi all hope you can give me some help with a strange idle issue I'm having with my 98 Ram 1500, 5.2 auto, 2wd. When I start the engine from cold it runs just fine, but after it has warmed up and I shut it off to run some quick stops to pick up things, I restart and it idles real rough. It almost dies unless I catch it in time and it smells real rich. It doesn't matter how many times I restart it as long as it is warm it do this rough idle. When I get going up to speed it is ok, but in traffic it is difficult to keep it running. I have changed the Idle air mixture sensor on the back of the intake, the intake gasket has been fixed and also the map sensor. I thinking maybe o2 sensors or? Thanks in advance.
