My 2000 svt does the same thing at times. How many miles does you car have on it ? Mine has 63K on with new factory long block with about 12k miles on it do to the crappy plastic water pump. The secondaries would seem to open up once and pull from 4K rpm+ then after that they would not open and the motor would rev with out the strong pull above 4K rpm's. then i removed the cover of the silver imrc or icrm box and noticed the top left hand quarter of the circuit board had a black burn mark on it , not on the silver circuit conectors just the top left portion of the green circuit board itself. this can't be good.

i lubed the gears with three in one oil and it ran great for three months. then the problems arose again. i lubed the gears again and now the secondaries open 70% of the time the other 30% the engine just revs. maybe i need a new imrc box or maybe i should replace my fuel pump which i have also had a lot of problems with . i'm going to get the
focus svt fuel pump as soon as i get the $100 for it from the dealer. it took the dealer 1 month to track down a fuel pump gasket the green circle one for me. at the moment i'm still using the old gasket which i fit back on the ring the best i could.

I believe the fuel pump is and important factor in the secondaries opening up. I'll let you know if it fixes it this coming weekend.

Does anyone know how much the imrc box with cable is from the dealer at retail price ?
