·Hey, I finally got the balls to take this car out of the city and on some highway, away from all my tools (the ones that wouldn't fit in the trunk anyway) and all the security of a quick tow-ride back home. On the way to my destination, I noticed something that doesn't usually occur at street speeds (WOT 1st, 2nd, 3rd, ...lol), ..in 5th at a 60+ roll or so, when I get on it partially or almost to the floor, the car will accelerate hard (like I intend) but then buck around a little bit.
Only mods are a shimmed wastegate to around 9psi, PVC piping catback, no EGR, iridium plugs, NGK wires, K&N FIPK, and a few other goodies that I really can't remember right now...but nothing in the form of fuel or ignition control, so the factory ECU is still in charge.
The bucking isn't terrible, its not like the car hits brick walls or anything, it just doesn't pull cleanly to redline like it does at lower speeds and in shorter gears.
My guesses right now are the iridium plugs might have incorrect gap, one of the plugs might be damaged in some way, I might have a clogged injector, I might have a clogged fuel filter, I may have an AFM that is oily from the K&N, I might need timing work, or some othe stupid thing that is completely obvious to you guys but not to me.
Tell me what ya'll think.
