anyone ever have a stutter from say 2800 to 3200 maybe 2500 to about 3200
it starts to build power than all off a sudden starts to bog bad even floored then when i get to about 3200 it starts building power again.. doesnt happen all the time but on a 30miles stop and go it will do it quite a few times.
i have timed my car, valve adjustment, rotor & cap. its done it since i put my motor in like a year and 3 months ago. any suggestions or has anyone had this problem?

 

oh and i have changed my plugs numerous times and i also dont have a stock oil sender hooked up but i have my after market one and it seems ok

 

Tons of us have that problem and have yet to figure it out.

 

do you have an AFC? Sometimes if they are set up incorrectly it wil cause your spark plugs to miss.
