Slow/jumpy rev counter

[kemp596]

Hope someone can tell me what is wrong, my girlfriend has recently got an 04 plate micra 1.2, one thing that i have noticed recently is that when accelerating the rev counter does not go up smoothly it seems to lag behind and goes up quite jumpy. The engine idles fine and the engine seems to run fine when accelerating. anyone know what the problem is ?

It'll be the signal wire I'd of thought

it can be a sign of chain problems apparently

 

[kemp596]

Timing chain ? Would that also not make the car not idle properly with revs jumping up an down ?? The car idles spot on an when accelerating the car is fine no kangooring or anything just the rev gauge jumping ? So could it definitely be the chain ?

Anyone know for definite what it is before the warranty runs out on it. Cheers

Can't be sure for definite without testing it ourselves.
If its got warranty take it in

Yeh think I will do. However he did say the warranty doesn't cover the clutch or cam belt. So if it is the chain I don't think he will cover it. Or is there anything I can say to make them change it due to it not being a "wear and tear" item like a belt

Belt tensioner? Not keeping tension on the belt/chain?
Still may well be the signal wire if it runs well

If he said it doesn't cover cam belt, get him to sort it after all there is a big difference be a belt and a chain

Loophole If you argue it enough, you should win, no?

Cambelt is not a chain after all as you say

like kemp says, warrantie,s never cover "wear and tear" tho, cambelt/camchain same difference the notorious QG15 almera chain issues often have jumpy tacho signs, but i dont recall it being mentioned on k12,s tho tbh ?

Could be a new epidemic
