Clio 172 hitting rev limiter early?

[dunc_sx]

Hi,

Problem is the car hits the rev limiter earlier in the rev range than it should, sometimes it goes to 7k but other times earlier, had originally thought it was a fuel surge problem but no longer think this. Put it on some rollers today and the fueling is spot on (have also checked the plugs), any suggestions?

Appreciated,

Dunc.

You have a warm up limiter of 6800 and a hot map of 7200 standard on these.

the car needs to be 'properly' up to temp for the higher limiter. I.e. if your car has sat around for a bit and then gone on the rollers - probably still on the lower rpm limiter.

The car is designed to hve an earlier limiter when its not up to temperature.

Is it up to temperature? Usuall takes 30 mins of driving I'd guess.

If it is, it mabe a wanky temp sensor or something.

Change thermostat. If its taking 30 minutes, something is wrong

Hi thanks for the responses, the car is fully up to temp and it does it at various rev ranges between 4 and 7k.

Thanks,

that sounds more like a misfire then. Plugs, leads, coilpack, injectors.....all suspects

Really feels and sounds like rev limiter to me, really obvious at 9:35 onwards on this vid, and I'm shifting MILES before the 7k limiter in this vid too (about 5k iirc)

You can hear it best at the end of the straight (10:10 and at 9:35) but pretty much everywhere else in the laps after 9:35 as well.
