Missfire cylinder 1 P0201

[Raymond_11]

My centre section exhaust rubber had snapped and exhaust was swinging about, then this missfire appeared then disappeared.
Now it's back again, I have tried a coil pack also tried injectors and swapped injectors round. Also took cylinder 1 spark plug out cleaned and gapped it.

I'm thinking lambda sensor but would this cause a constant missfire.
It did come up a fault code for lambda bank 1 but didn't come back after clearing.

Any help would be appreciated.
Thanks

You sure you've changed no 1? Renault number them back to front so no 1 will be gearbox end

Just checking lol, injector loom isn't damaged by any chance is it?

 

[bloke]

did you clear codes after you swapped injectors over?

 

[Raymond_11]

Injector loom looks fine but not tested it. Yeah cleared codes afterwards
