The engine light!!

[Y@Heart]

Hi guy's, I'm new to this site and to Renault.. I've bought a Clio Cup to make into a track car!, I think the car's already been
Mapped! as it doesn't hit limiter until 7500/8000RPM.
I've put a De-cat on and thats when the trouble started! put a code reader on and first one was P0130 sensor1 Bank1 Lambda
second was P0135 heater1 bank1 not a clue??? and the third was P0120 throttle/pedal which I've sorted.
any help on the P0135 would be nice!! thanks IAV..

First two relate to the lambda sensor - the precat one.

Cheers Amos, I was told at a rolling road that if I put an extention on the second lambda with a small feed hole it would put out
the light?? which I have, and it hasn't so it's the precat one not the second one..

Yeah the second lambda would be bank 1 sensor 2.

You can try swapping them to see if the fault is with one sensor or pick up a Bosch one from ECP.

Not to sound thick! but who's ECP???

Swapped them round, lights stopped off but still when warm gets a misfire so taking the inlet back off to check plus and leads are all ok!
was new when I got the car in feb, but you never know..
