funily enough mine didnt smell rich but was going through a tank in 200 miles no matter how i drove it
And since changing the cts, everytime i start it stinks of fuel the lambda really helped on mine as it as knackered and came out black as the ace of spades so i'm trying to stop the overfuelling before i knacker another lambda

I'm going to try egr tho and hopefully that will sort it for good, and will hopefully stop this poor idle i've got, if not my mate told me about some laser cleaning or something he had done on the injectors on his crx, apparently it dropped his hydrocarbons from a few hundred to just 2 and thinke he said it only costs around £80 worth a punt imo even just for making it run cleaner

the cat wont actually stop it from overfuelling, overfuelling actually damages the cat so it probably has failed, but it would get you through an mot just be brute cleaning force, but would still have to sort out the overfuelling
