changed plugs checked wires and coils cleaned egr and iac valve replaced pcv valve alternator pushing 14.2v at idle checked for vac leak.... still rough even sometimes jumpy at idle has only died once no codes being thrown no check engine light... maybe the fuel pump???? any help would be great thanks

 

try checking the intake hose for cracks the big black one.. it seems to be a big problem on these cars and a new 1 is about $40

 

Try replacing the fuel filter and cleaning the throttle body if you are still having a problem
