172 cup rev limit?

Car  clio sport 172 cup
right my 172 cup used to rev to about 7.4 rpm and now it seems to have lost some revs :S hitting the limit at 6.8 rpm now, anybody got any ideas as to why its doing this now?

cheers lee
 
yeah its still doing it when upto full running temp, i changed the battery last week as it was fooked could that have anything to do with it?
 
hi whats a coolant temp sensor problem. as mine has a coolant symbol come on at the side of the speedo . where is the sensor on the engine... thanks garry
 
Max. engine speeds for a coolant temperature < 75°C 6,700 rpm
for a coolant temperature > 75°C in 1st or 2nd gear 7,200 rpm
for a coolant temperature > 75°C in 3rd, 4th or 5th speed 7,000 rpm

Could be CTS, or thermostat, does the needle sit just above or just below or bang on in the middle?

Are you trying it right after the needle gets up to temp.? Or are you giving it a good 20 min run before trying it?

IIRC the sensor/trigger for it is based on oil not water temp. as displayed on the dash, and oil temp takes a while longer to reach optimum.

How old is the oil? Needs the correct grade and nice clean oil for the dephaser to work correctly.

not sure mate but the dephaser is quite noisy when engine is warm,so i know that is could possibly need changing but got some oil and filter and a flush today so ill get that done at weekend and see if it helps at all,also got a new cts so ill whack that in also.

cheers for help everyone
 
mine has a slight MPG problem. it revs to 7250 though, but the temp gauge on the dash keeps moving from just under the middle and back to the middle again (even after 1 hour of normal driving)
what should I look for at first? (lambda will be changed in the future) are these symthoms likely related to the CTS or the thermostat?
thx!
 
anyone knows the part numbers on these? wanna buy them from renault
sorry for not mentioning in the 1st post
 
Changed today these two, here are the part numbers if anyone's interested:

thermostat: 8200 772 985
CTS: 8200 561 449
thermostat gasket: 8200 267 272
the new thermostat came with a new gasket (wish renault knew that before advising to buy it! :mad: )
