I am at wits end guys, I don't know what to try next. I have a 4g63 w/cyclone intake, and stock freebie mods. Except for the 3" exhaust. Everytime i put my foot to the floor it feels like I've got a hundred mph head wind. But if I back out to about 1/2 or 3/4 it takes off like I have NOS. I don't understand this at all.



Next is on a cold start it will idle just fine. But as soon as it starts to free roll I get a high rev and it like a rev limiter kicks in up and down, Until I bring the car to a complete stop. Now my Q. is, I have two ABS wheel sensors that are bad one front one back, could this be the reason for the high revs in the morning on cold starts? :confused: :cry:
 
OK, I hope someone can help me. It's a pain in a parking lot, Because you never know when that little boost is coming. :talon:
