Hello everybody! I have a 2003 Sambar Van. I have done few maintenance tasks at my own and love to do so with the help of your kind help and suggestions. I learned good tips in these forums and hope that it will be continued. 1. I am not sure that my van engine is supercharged or not. It has throttle body, different sensor installed on intake manifold and fuel injectors but the V-belt has three pulleys (Engine, Compressor and Alternator) whereas the V-belt of supercharged engine as shown in the service manual run over more pulleys. So what if it is not SC, is it equipped with carburetor? (BTW I don't have the manual, just read few pages of it on Google books) 2. Fuel consumption is too high (about 11 Kilo meters/Liter) so I tried to clean the fuel injectors. But these injectors are not as simple as others. They have holes in center and the procedure I learned from tutorial videos could not be applied. Please suggest any simple method of manual cleaning. And do you suggest to add injector cleaner (like STP) fluid in fuel instead of manual cleaning? 3. What is the location of ECU or computer in this Van? Thank You Very Much for this help.
