Yaris Problem..Please help (Engine cuts out 3k revs)

[Lauramay1980]

Hi there,

Was wondering if anyone can help please. I have a 1.0L X Reg Yaris and recently when i hit around 3000 revs (in any gear), its like i'm bouncing off the rev limiter and the fuel cuts out.

It's acutally at a toyota garage at the mo, but has everyone there baffled,as they have a error code P1315 (misfire they reckon). They've tried new spark plugs, swapping coils from a donor car, continuity checks of all of the ignition wiring, and fuelling checks, but still no joy

Has anyone had experience of this before ? I don't want to keep throwing cash at it at the dealer !

Thanks if anyone can help, or has any suggestions of what it could be?

Laura
