Hi Ronnie, the method described in the site is for pre 98 models only,these are known as "flash codes" later models have the worldwide standard 16 pin EOBD connector which is located under the dash to the right of the steering wheel, and the only method to read the codes is with a code reader/diagnostic computer, if would like I can mail you the info on your system contact me on nige110162@hotmail.co.uk as a shot in the dark i would go for either the coolant temp sensor or the crank speed/position sensor???
