I've got an 04 TJ with the 2.4L engine in it that i purchased this year. I enjoy the little 4 popper a little more that i thought i would, but the one ? i have is, why does the motor seem like its sucking air thru a straw just off idle? I havent done any performance mods as of yet, because there's not much out there for the 2.4L. The only thing i can think of is, there is some kind of flap in the manifold that restricts air flow some, but im not sure. I know some will say to regear, and i may regear in the future after i install 31's on inplace of the P225/75/15's on it now. But the 4.11's in the jeep, pull hard in 2nd and 3rd while the motor wind out. Theres got to be a way the give the 2.4L a better throttle responce, so if anybody has any ideas on what to do about this, (Please Advise)
