hi my car shakes when on low rps and i am getting code p0401 thats something to do with egr sensor or it my be like spark plugs and wires or coil? feels like cylinder misfires if thats that egr sensor where its located and i can i clean it or just need to be replaced??? thx a lot

 

could be your egr vac line popped off....

its bolted behind the intake manifold and looks kind alike your fpr....u may have to remove the top i/c hose to get your hand enough room back there to feel around if the hose is off..

man someone just posted a pic of a diagram too that i saw yesterday but idr the name of that post

 

but the prb is that its not always doing this it does it only after driving couple miles
