EM1 losing power at hign RPM

[FTVZimmy]

Hey everyone, Recently my car has been running weird. If i give it gas and rev it high the tvec kicks in fine but then around 6000 it feels like as if im letting off the gas, then again at about 7000 the power comes back then again about 7500 losses it again and power comes back. i notice this just the other day. other then that shes drives like a dream. Has anyone had this problem with their car losing power at high rpms?

p.s. sorry about the header, my bad..

at what RPM does ur "tvec" kick in?

between 5 and 51/2. ill check on the plugs as soon as it stops raining...

sounds like either your plugs or your primary o2 sensor. do you have a CEL?

no codes at all, i run the odb2 on it every now and then just to check. and i always look up on alldata.
