Alright it's a 04 build in September of 03 had to put a ficm in it and did have the injectors so far the easy side was alright for a bit now it will run ok sometimes then go to **** won't take off till rpms get up which takes a minute real sluggish then goes and shifts pretty hard sometimes will miss like cruisin and a cylinder will intermittently miss not throwin a check engine light but has egr codes in it for throttle plate and egr itself along with a cam sensor (already replaced that) and injector 2 and 3 (already replaced 2 but it's back) and advice is appreciated can't keep throwin parts at it
