Hi All, i have a 1993 WRX import, standard, and the fuelling is miles off, failes emissions on Carbon Monoxide by a mile etc, have been advised it is the lambda sensor, but i am not sure what type to fit, the one fitted is a universal one, so pretty sure thats the issue.
Cheers

Have a look and see wether its a 3 wire or 4 wire buddy, universal ones have a habit of not lasting long. There's loads of both types on eBay for around £20-£30 for a used genuine. Failing that I should have one knocking around, just send me a PM.
