Idle..good..driving..bad
Ok, this started by chasing an idle problem. Had checked and tested TPS, its good. Cleaned and tested IAC, its good. New EGR valve. Cleaned out whole throttle body, and made it look a little prettier too 
. All vacuum lines are new and good.
Now the idle is fixed, but now driving down the road cruising at a constant speed (any) where the throttle is at the same position, the engine starts cutting in and out. Is this something wrong with the TPS? It didnt do it before I did all of this stuff.
