still having problems with the 8v



sounds like you should check the intake boots, you may have a crack in one 
of them. when you hit the gas, the torque form the engine expands the crack 
letting air in past the sensor plate and leaning out the engine which then 
doesn't get enough fuel to run so it slows, then the crack closes... 
starting the rocess over again.
