Getting bad fuel economy so im gonna get my injectors cleaned, but then i read that a black exhaust tip means that its running rich, so maybe it's the O2 sensor thats at fault? (even though it doesnt report any faults with a diagnostics check)

Check the pics...




That would be considered running rich?

looks like 9yrs of carbon collection to me. Clean it off 100% then take a look in a few days. Or get a dyno run organised

It's the unleaded fuel that make's the tip stain black, the leaded fuel's used to go grey, this is normal.

City driving with stop,start traffic will cause the tip to go black. Go for a good 20-50 km drive and then assess the colour. ps. Give the chrome tip a good clean with steel wool and plenty of water, inside and out!
