Misfire & Lambda (O2 Sensor)

[MarcB]

My car keeps throwing the EML on and its doing my head in.

The car has a slight misfire due to cheap plugs and maybe a stuffed coil pack and due to this its throwing a lambda fault in also.

As i have stated in a post before when i bought my car the ex owner said it had been remapped with the RS tuner to rise the rev limiter to 7500rpm and when warmed up it does go all the way to 75000rpm

Been told by a tech at work that my lambda fault could be down to this remap as it could be throwing fuel into the car and it might not be mapped correctly.

Does anyone know how i could get the correct settings from factory back on my car ??

if it's really mapped with the rs tuner module I'd contact Henk at fastchip and for sure he'll be able to give advice or to sort the problem

Try changing the coilpack first, that's relatively easy to do and not too expensive. Just take the engine cover off with a torx screwdriver, undo the 10mm bolts with a socket with extension, and swap in a new one. Takes 15 minutes and around 40 pounds?

Misfires are inevitably going to mess up your lambda readings

Im going to change the Coilpack, HT leads and spark plugs for genuine renault ones.

I will aslo do the above and E-mail Fastchip.nl to see if i can get any help from them.

Thanks for the info and help guys
