There is , I believe, a gearbox shift point be fudllmemt as well that I don't think I've experienced having driven it.

The gear box issue is difficult to explain but I know chris felt it at the higher end , while driving it both normally and pushing on it will go to change gear and you get what feels like a push/pause gear changes up then away you go.

another way I have tried to explain it is just as it changes you run over a bump in the road.

Ah ok. Same thing then.

So both intermitant, and both occur roughly together, or not at all ...? Generally speaking?

1 rev counter jumps (both in neutral and in gear)

2 Hesitation under power

yes both are intermitant seem to be together.

rev counter jumps both in nuetral and in gear from 0 to 1000 revss depending out how hard you press the pedal.

no hesitation under power from what I can feel

Are the revs jumping with the rev counter, or is it just rev counter jumping independently of anything else. If latter, don't rule out instrument panel failure, and unrelated to power/gear glitch.

Revs only jump when you press pedal

[chrisgixer]

Engine revs seem absolutely normal when the Rev counter jumps.

That's to say there is no difference in engine noise and response on any occasion, yet the needle jumps intermittently.

If it was just this symptom then yes I'd swap clocks out. But the inference is that the hesitation at high rpm also seems to rear its head at the same sort of time. As if the two are "possibly" caused at the same time by the same thing.

I think Pauls is fairly convinced the two are related sonehow. Although may not be.

Have you got an old analogue meter to check voltages at the point this happens?  Looking for voltage spikes, particularly from alternator?

[TheBoy]

Any overvoltage codes ever stored in any ECU?

No I dont have a analogue meter.

No codes stored.

Update..

Had battery and alternator tested at kwik fit. All came back as working as it should.

Now what??

[pauls]

Since replacing wirring loom about 2 weeks ago this has raised its ugly head again. Did pedal trick today and no codes.
Any new thoughts please.

P.s. i dont know how or why it went away
