Ok I did a search and don't see this one so I have a 3.3 rough idle pull the intake check the injectors all 12ohm alright put everything back together engine red lines on start,

Pull the throtle body check resistance on TPS, good. I have no idea how to check the idle air motor and don't think it can red line the engine any way. pulled the map sensor, replaced it same thing, leave it outside the intake hits 3k and stalls. What else is there to check all vac hoses are connected.

I need help. please

 

Just an update no codes either.

 

You may have a vacuum leak, from the egr tube. Or missing gasket.

 

which gasket ?

egr hoses are pretty tight.

 

master tech your the man. Plenum gasket was destroyed replaced it runs like a clock thanks.
