Jazz jerks and cuts out in D but not in S

[soongster]

"D"-flashing.

lol had a little snicker there

Coil packs can be eliminated as well because under WOT the car accellerates properly.

When the coilpacks on the missus' jazz fried, I was getting jerks at initial acceleration, with no problems after the first initial jerks, even in WOT. So personally I won't rule out the packs yet. But I know how costly the mofo'ing coilpacks can be.

What about dirty injectors? plugs? leads?

other than that I can only think of more sinister things happening in your gbox, clutch.

sorry am of not much help
