i guess you could call it hesitating anyway?

Basically, my saff has just started, erm, like dying momentarily while crusing/driving under 2k rpm, its only for a split second, but its enough to make the car lurch abit, just a total loss of power, at the exact same time, the rev counter drops too, any idea?

Its 4x4 on l8 ecu, running closed loop and coil pack, could the TPS cause this, as i know the wires going to it are iffy (job for this week!)

Thanks!
