Well replaced lift pump and thought if might fix problem and still when revved if like misses in the low to mid range and once revved in to upper range it is ok. But at cruisin speeds it sounds like it is runnin off all injectors then it will sound like it is runnin off like 3 or 4 and also it feels like it has lost lots of power. Does this mean my injector pump gettin ready to say goodbye?

 

did you check for fuel leaks or are you getting air in the system some were.

 

Yea and there is just one at the fuel heater got the o-ring to replace so I am going to put it in tomorrow and see if that may fix but I am not so sure that is the problem cause it has been leakin for the past several months and never has done what it is doin now.
