He He. If in doubt, give it a good spanking! A proud graduate of the Italian school of car care!

Hi all just had a look at the website for Cataclean and seems like a good product. I have found a stockes near my work and was thinking of runing up a trying some at lunch

What do you guys think of it it,s £16.50 Having the 02 prob as its seem most of use are with the 3.2,s.

Thanks.

What do you guys think of it

Got to be worth a try, I guess. Like most lotions and potions for use as additives they make some impressive claims. Whether it's snake oil or not remains to be seen. At least you have a problem at the moment, so you will have an idea whether it's done anything or not.

I am sure the use of a few resistors or resistor-zener setup would do a nice job of keeping the ECU quiet.

I wonder if the ECU is clever enough to look for activity on the post-cat sensor when the cat is cold, and verify that it disappears when the cat gets hot, or if it is enough just to never have any activity...?

Just to get this right when you talk about pre and post 02 sensors is that going from under the car looking towards the engine so the 1st set are the pre and the ones after the bend are the post or is it the other way around. I belive that one set stay at one reading and the other set swich from lean to rich would that be right.

Thanks

The one closest to the engine (above the bend) is they mixture control sensor.....the one between the bend and cat is the monitor sensor
