ok, like if you slowly accelerate with my car it starts climbing up to like 1300-1400 rpms then drops like 200 rpms for a second then it will start climbing back up, i know my SES light is set cuz my fans kick on at startup but my light is burt out, anyways i dont think im getting great gas millage either, but it seems for a min it gets to much gas, any ideas of whats causing this? i already put fuel injector cleaner in my gas a couple times and it didnt really help

 

What does it do when you floor it? (need more info)

 

i havent really floored it cuz im still breaking my transmission in, just put a rebuilt one in, but i think ive got enough miles on it now to give it a lil, ill see what happens and let u know
