Well guys, I used this cataclean stuff in the hope of getting the emissions down. i gave the car a good run for a couple of weeks. And before i got the emissions tested today i covered roughly 200 miles. The car was hot really hot when it went on the test infact so hot the fan kept on coming on.
The CO emissions was .70 so a fail. Before the cataclean and driving it it was 0.8. So not much of a difference.
The guy who did the emissions test today said to me all the readings seem to be right like the lambda, cat, HC apart from the CO. He said normally when CO reading is out its due to the ecu unit. So he told me to take the car to toyota dealers or something and they'd be able to sort the ecu problem out. he didnt think it was anything major in terms of cost.
So, what do you guys think? do you know anyone with the equipment to do diagnostic tests on altezza's?
