car bucking when going WOT from low rpm's
This is just a small little problem ive been having since buying the car... If I accelerate at WOT from low rpms (1000-2000, sometimes even from 3000) The car will let out one prononced (buck) and just continue to rise throught the rpms.
It never happens more than one time per throttle application, ever. It is feels like the buck you might get if you let off the throttle in 2nd gear at about 4500 rpms then applying it quckly again. It's like the ignition just cuts out for a split second.
Also, I dont know if it's related but the car dies if you sink into the clutch coming off a hard throttle application (such as a dyno pull)
Im placing an order at paragon today for some things I need, and I was going to buy some parts to start trying to fix this while I'm at it.
What should I try replacing first? Spark plugs/rotor/cap/coil, or speed and reference sensors. Seems like it is a reference sensor problem to me... Replacing the sensors might be a good place to start right?

Check the TPS! Disconnect the O2 sensor, does it make a difference?
