yes, pulls hard after. like i said, only occasional happens when car is very cold for a few minutes at low rpm's. dunno bout the fuel injector, i had this same problem last winter and it was gone in summer now has come back. its just a little annoying, i can live with it but wanna try to fix it. hesitation and popping sounds at low rpm's when cold, especially when you step on the gas. goes away in a few minutes. also, i dont have cats
