car lacking power when high rev

[ajaz]

Hi,

I have a clio si 1.6 (1999 model) and when i put my foot down the car seems to hold back on the power, its now impossible to over rev the car im hopeing it could be just the catalyic converter but any ideas ?

 

[ajaz]

Well it seems to not like putting my foot down while driving but will drive fine low revs and while idleing and rev`in the engine it seems to rev fine.

could also be a sign of a worn clutch, and is it pinking at all at higher revs?

 

[ajaz]

its not clutch it was done for the mot and it only does it when im moving and trying to get more speed, i can put my foot flat too the floor and it gets worse, if i just put a little power on while driving its drivable and seems theres still nothing wrong with reving the car when its stood still absolute no holding back with revs then.

ive put in the wanted that i need a new dcat, hopefully this will sort it, if not im selling the car :/ just cant afford to keep spending and spending and would sooner let someone know what there doing sort it heh

Clean the throttle body? Does it do it from cold or only when it gets warm?

Im having the same sort of problem..got it on the diagnostic machine and it says my
o2 sensor before the cat is knackered.

recently..

i will punch the throttle down hard either from stand still,or going a long at any speed..and nothing at all will happen...and then,bang! the throttle will kick in..like a turbos just kicked in or somthing and it will push quickly foward like its got a delayed reaction-like its got turbo lag or somthing....its onli a 1.2 16v..but i dnt no wat it is...and neither do renault..
HELP!!!!

Has it got a std air filter? My CAF pipe collapsed and gave similar symptoms to the original posters
