HI i had couple faults wit my 2001 bugeye wrx one was maf which i got new one and has fixed it but have another code p0031 which was told 1st lambda sensor which i replaced with a universal one but code still there n think it running bit worse ,,,do universal ones work or need get genuine one or is this not the fault , thanks

 

Should Have bought a denso one mate

 

buy cheap and buy twice as above denso ones are the best aftermarket cheap ones often dont work or fail quickly

 

were best place get one n how much

 

Google it mate or ebay £97

 

Iv heard others use universal ones and all is ok but may not last as long,i used a denso one mate on my 02 sti and was only £100 so not too bad.could be the wiring thats at fault but would need to be checked out to confirm.

Try them

 

Bugeye uses a pseudo wideband sensor and therefore the ECU looks for the OEM jobby and doesn't like universal (narrow band) jobbies............
