Hi.
I have a 1998 Spanish build Vitara (not Grand Vitara).
Its with G16B engine with plastic intake tube and distributor(85C designation).
There are few strange things with it.
I found spark timing don't freeze with jump wire between C-D. Yes it stays still unlike without the wire but when I race the engine timing advances.
TPS is ok and adjusted right, coolant is hot, rpms are 800.
Another one: when engine is at normal temp, and I cruise at stoplight at idle(manual trans), rpms are 1000 or above. Few seconds after the car is still, rpms drop to 800. I've used to have 1992 G16B Sidekick(again Vitara in Europe) and it did not have this.
I read EGR on newer are speed dependent. I suppose ECM increase engine speed so it don't stop when exhaust gases enters intake.
My fuel consumption is bad - 23MPG at 50-60mph country roads and 15 MPG in city. These MPGs are on LPG, its normal to be 10% lower than on gas but still too low.
Any thoughts?
