question on hesitation
as i take off normally driving in street traffic, the the car starts to pull, then the engine acts as if there is no fuel, pedal in same position, then it starts to pull again. i basically loose power for a split second and then it begins to pull.
If i throttle through then the hesitation isnt there. i have no codes. what could this be? i am starting the suspect the oxygen sensors but that would have shown as a code wouldnt it? or the possiblity of the throttle body actuator.

Maybe is has to do with the fuel system. Clogged fuel filter, or faulty pump. Just a suggestion. Those could have to do with hesitation, but in no way can I support this as a cause of your problem.

That's what I was going to say was, maybe run some Techron through it and see how that works. If you don't run fuel system cleaner often, then you'd be amazed what the first bottle does.
Btw, you'll only get O2 codes thrown if the values they are returning make no sense to the rest of the system. Like, if the system inputs fuel and sees no resulting expected change, then it'll throw a code. Most times, it will keep going till it runs like crap before you see O2 codes. Honestly, they're more of a preventative maintenance item in my book.

fuel pressure stays at 58lbs, run nothing but chevron. it starting to point to the throttle body actuator. ill pull it and watch the plate as i move the pedal to see if it is sticking
