| The whistling noise is quite common and is from your turbo charger. If it is very loud check for damaged or cracked hoses to the turbo. It can sometimes be just a small pin hole. The changing up or down with a slight bit of acceleration or increased load sounds like you need to blank off the 2 EGR(exhaust gas recycling) valves. They were fitted to accomodate strict Japanese emission controls and are a waste of time. They will be giving a false reading to the throttle control unit and causing your problem. Simply take the valves off , make a plate for each to blank off the ports and blank of the hose to each valve. It will improve your truck immensely. If you are not familiar with this truck I suggest you go to this website where you will get all you need to know about the Isuzu. They have a full range of instruction/photos and experts on hand to help you. There is no charge. You will also be able to download a full workshop manual from them. WWW.ITOCUK.CO.UK |
