01 f-550 7.3 loading up/running rich?
hi I have a 2001 f-550 7.3L psd 6 spd manuall trans. with 115,000 mi. on it bone stock. It starts and idles fine the problem is once i give it throttle it sputters loads up pumps out massive amounts of grey/white smoke. i can floor it in neutrall and it slowly stumbles its way to about 2500 rpm then she clears out and screams up to 3000. I have checked blow by and its not ecessive. changed injector o-rings, ohmed out, cleaned and checked every sensor on the damn thing. have AE scan tool, has no codes. no check engine light. no ses light. It has 55-60 psi fuel pressure. I have ohmed out vc gaskets, under cover harness', harness between idm and vc plugs every thing ohms out good. it has a raw rich eye burning smoke. I am at a loss with this thing so if anyone has any ideas im all ears. thanx in advance.
