I`ve got a 1999 Carina/Avensis with the 2.0 petrol 3S-FE engine and manual gearbox. Milage around 155.000. I`ve got a problem with the engine, its not running smoothly when I have very lighte trottleopening. Ex. I drive on constant speed in high gear, and reduces the throttle gradually to lower the speed. When the throttle is almost closed, the engine starts "clogging" and not running smoothly. The same if I drive down a hill without throttle in ex. 5th gear and need to open the throttle just a tiny bit to maintain my speed the engine starts faulting in the same way. There are no problem at all with the engine when I have more throttle and it is pulling heavy, it runs smoothly and fine.
I`ve tried to change the sparkplugs, airfilter and have tried to types of fueladdetive system cleaners without results. The problem seems to be worse by every day that goes. I had the local garage to take a look at the car. They runned an engine diagnosis but there were no fault-codes registered. They ment the problem was issued to the fuelsupply system rather than to the ignitionsystem, but didn`t look deeper into it because I then had to pay a lot of money.
I hope someone have som tip for me on where to start looking. I`m very greatful for any answer :-)
Sorry for my bad english, I`m Norwegian.
