I am having problems with cutting out after starting. If you keep your foot on the accelerator for about 30 secs once started on slow tick over the engine runs ok. 

This doesn't happen all the time though. The garage I went to said the fault code said it was The Pre Cat O2 sensor.  Anyone have any idea where I can obtain one of these please

hello john here is a link on ebay for the pre cat sensor https://www.ebay.co.uk/itm/384959839140?itmmeta=01J5DPF8KCDKX78FXG6G6SF1SK&hash=item59a164fba4:g:pA0AAOSwrR1kFCuN  this gives you a image where its located you got 2 pre cat sensors one on the front of the engine one on the rear of the engine both the same part no. 

hello john do you do a lot of mileage or is it mostly stop start driving 

Hi it varies, it's our main vehicle so around town but quite a bit going to Yorkshire for baby sitting duties from Newquay .

 

Cheers John.

Many thanks, it certainly looks like the right one. Have one one on order.

 

Regards John

 

john also get your self a fuel injector cleaner one that cleans your cat and fuel system i add a bottle once a month this will clean your fuel system and clean the converter and oxgen sensors 

Good idea, will do.

Regards John

Hi, I've been reading through threads and hoping I can jump in on this one. I've failed mot on emissions. Garage is saying most likely cat converter but could be the pre cat sensors thst you've linked to here. Do I just ask them to check their computer? I've been looking for new cat converters and can't seem to find any. (Have looked on jap auto spares and partsouq...)

will phone toyota tomorrow but assuming a new cat converter is pricey anyway, let alone from dealer!

 

Any helps appreciated, still not sure how much I trust the garage as I'm new to the area!

Hi there!

Without actual detailed specifics on what emissions are out of kilter, and just how far out, not that I'd know what it meant in honesty, I would be very tempted to try a fuel system cleaner.

I have used "CataClean" in the past, not for an MOT fail though ,and it felt like it made a bit of difference, but of course it could be I just wanted to believe it!

Perhaps check reviews of ait and some similar products?

Best of luck!

I agree with bignev I have helped a few members on here having same issues with emissions use a bottle of cat cleaner about a quarter tank of petrol and give it a good hard drive it makes a difference I put a bottle in mine every month on a 3.0 v6 and never had a problem with emissions very rare you need a new cat then try a different garage for your mot I had my cats changed because they was stolen when it was having a engine build 6 months ago I paid about £400 each brand new from America and it was quick shipping if you need link let me know .

Ok thanks both.

Picasso I had read your advice on that before but had used cat cleaner in a full tank, which I thought was the packet instructions. I'll give that another go though then before shelling out 400! 

I have the same engine, 2003, could you possibly send link in case I need it? Just trying to get everything back together to be ready for redoing mot! 

 

Thanks again, will keep updated

Ah yes, depending on the one you used that could have been correct, but I know the actual "CataClean" brand is put in to a "small" amount of petrol in the tank!

pm me your reg no. with yours being a 2003 i think they may be different to mine as yours a lot earlier tha mine

all cat cleaners reconmend full tank never done me any harm what you need to remeber it dilutes it so thats why i always say at least a quarter tank ok if your not having emissions problems full tank ok 

Maybe others are for a full tank, but not CataClean, its different. Please take a look at it, I've screenshoted one description from ebay.

Ok that makes sense. I'll send it through with that quarter tank then and give it a good blast. Fingers crossed thst blows some filth out of it!

Thank you both

I'll keep my fingers crossed it works for you!
