(lol cuz i was to lazy to do it) but the thing that gets me is that while im crusing at any speed, in any gear my car surges as if i am tapping the throttle. i usually notice this when the car is around 2000 rpm. the idle isnt bad either like every now and then it surges but mostly when i first start the car after it has been sitting for a couple days. a random note is that ever sense i got my hci setup the car seems to have a harder time starting. for example i have prime the fuel pump by cycling the car on and off a couple times to start the car after it for a few hours. i am suspecting that it might be the tps, iacv, or fuel pump. the only reason that i am leaning away from the fuel pump is that when i step on the gas the car doesnt stubble at all. oh and yes i did get the car tuned after the hci setup and my mechanic says that the car might just need some fine tuning after i have been driving it awhile and everything settled in?</p></blockquote><p></p>
