Could it be the fuel filter? Also my idle is high then low then just right. Changed my EGR the vac line and the sensor, the tps, o2 sensor and the iacv. Nothing has fixed this problem. But I did see where the vac line running from the carbon cannister to the cannister purge solenoid was not connected.

Well I FINALLY figured out what the problem was. Unfortunately it was after alot of replaces that didnt need to be done at a cost of around $400. Turns out that it was a stupid plug. Ive never seen a plug this bad. Carbon and rust all in the concaved area around where it sparks. Idk what its called. Now shes eatin pavement again. Thanks for the help.
