  1. The 2kreeks hauler has been missing at hiway speeds 'cruise 50/65 mph' every other speed is ok. If truck is acelerating no problem, pulling hard 10k up everything nornmal. The lift pump was replaced approx 3500 miles with a generic AIRTEX BRAND. This was replaced during a oil change when I found out the new carter was starting to fail. Now with new instruments the fuel pressure at idle is 21.5lbs and wot is 16lbs. My basic idle time is approx 5mins and some time more depending on how long of pull and how heavy..Does this high of fuel pressure hurt the vp44?Could this high of fuel pressure cause the missing?Only codes showing with key trip, is 1693 which was left over from a p0122, which is gone now after replacing the apps.larry
