engine hesitation

now that the intake is fixed, i can have also found out the the engine has a hesitation when i start off in first and also when i am just excellerating through gears (most of the time it is very slight, but when i start off in 1st it can be worse.

once again Thanks in adavce for any helpfull info.

when did you replace your plugs, rotor, cap, and fule filters last?

probally like 15000 miles ago i did plugs and wires, (and no cap and rotor) i have a coil pack, and everyone has told me that the coil pack is either good or bad there is no in between, but when it hesitates i feel that somthing in the engine is not completing a full motion (sorry thats that best way i can describe it, i think i am going to do a fuel system cleaner so injectors and everything can be cleaned
