Lambda sensor?

[joej9]

If my car is kangooing quite and a bit and poor acceleration, is it a buggered lambda? It's a 1.2 mk2 ph2. Apologies if it's been covered. Thanks in advance.

Can anyone help? Going to pick some stuff up from a lad breaking a Clio tomorrow and I told him I need te lambda sensor. He then asked which one, which has confused me a bit. Can anyone shed any light.

Thanks.

could be... are you getting any lights up on the dash? co2 light?

There is pre and post lambda - pre will effect running of the car if faulty, post will just bring up the light on the dash if faulty.

Could even be a blocked Cat on the exhaust? That will choke the engine and cause it to do that.

 

[joej9]

no lights on dash at all. When the car is stationary and I rev it, sometimes it sounds like a misfire from the exhaust. Could that mean a blocked cat? The lad breaking the other clio only wants a tenna for the lambda so I may as well get it while Im there. I'll message him and ask for the pre lambda.

thanks for the help lads it's greatly appreciated.

just a little update, I changed the coil pack for a genuine renault one today and it seems to have done the trick. no more kangarooing or misfire. revved the car when stationary and still there is a sort of backfire. i think the cat is buggered? not to sure where to go from here or how to fix the cat or even check its on its way. any help appreciated.

cheers

Did you replace the HT leads and spark plugs?

You can also get CAT cleaner that try's to clear any shite out of your car that may help my mechanic said to me when in doubt smash the cat out and buy another when your close to MOT time haha ignore that advice though

I changed the leads as they came with the coil pack but I didn't change the spark plugs. Running a million times better than previous.
