Toyota Duet Idle RPM problem

[Mirza967]

I bought a duet 1998 model. Now the engine checklight comes on sometimes. It cannot be diagonosed by toyota as the OBD system is for year 2000 and above cars. My mechanics cannot identify the problem so looking for some help. I have not clue about cars as this is my 1st one. I have changed the air filter, the oil filter and the engine oil...

Now when the car engine checklight comes on I feel a drag as though air is going in my engine and I loose acceleration. When I press the acceletor pedal hard things become fine and the light goes off.

My idle rpm is currently 1300-1600. and I have noticed a drop in my fuel efficiency. Please suggest some things that I can try... the parts are very expensive here and I have no idea about the car... so please pardon me if I ask you things again and again....

this can be sorted out by hit and trial.....try changing tps most probably if not then MAP or MAF whichever present.

I would start with getting the fuel injectors cleaned and fuel pressure checked.
