95 gmc 332,000 miles. TBI 5.0. Doesnt start right up when cold, intermittent whule driving and whrn on incline nose up it has hard time starting. Now the egr was bad deleted that runs better than it did cleaned alot of gunk out of throttle body itself, replaced fuel filter that helped as well, i think the throttle body itsef needs a cleaning and the fuel pressure regulator replaced or could this be a failing fuel pump
