Normally they have a crimped stainless tie.
Plug in diagnosis, early models use the TIS (Toyota information system) later Standard OB2. The Lambda sensor could be faulty.
Good thing about Toyota is that most things are cheap and easy to fix

Thanks Darren, Mine is a 2000 yr model but it has the 16 pin plug though, so i assume its OBD2 Ive ordered a OBD 2 reader it will be here from Amazon tomorrow I will have a look at the codes before taking it to the garage.
Its been a while since I had my head under the bonnet of a car, I probably wont be fixing much of the oily bits myself on this one either. I was contemplating buying a trolley jack and some axel stands earlier, but I dont trust the cheap ones and I am not so sure that the expensive ones would get enough use to become an investment. My garage has a pit but I filled it with rubble after I fell in it and broke my arm (the wood on top was rotten) but knowing the fault ahead of the garage is worth £26.00.
