Engine problems

[Jonny112]

Hey all,

I have a 2000 1.4 8v clio sport, My problem is when the engines cold the car performs and revs great but when its hot it seems to be holding back

anyone any ideas

the only mods i have is a big K&N air filter

Kind regards

Jonny

Get it on a diagnostic setup... Could be an H02 or a CTS issue

Lambda (Oxygen) sensor, or Coolant Temperature Sensor.
