2 issues,
1: MPG, you failed to say MPG, 15mpg? or 39? is 39 low?
what MPG? you never said it?
2: rpm cruise. (what drive line, A/T M/T ?) what tranny?
first google hit , is this it? this yours?
engine: 1.5-litre 4-cylinder petrol, 75 kW/133 Nm
Transmissions: 5-speed manual, 4-speed automatic, FWD
3300 RPM in 5th and 100km
if you wish to now what is normal, find the final drive ratio, listed in the FSM. Id say this is normal. typical of tiny engines, with low torque.at lower RPMs.
if you have the A/T and IF the trannywere to slip, the TCM will infact throw DTC codes, telling you it did.
IS IT? (scan tools show you this fact as might that glowing CEL lamp on the dash, on driving.
RPM
my 1.6L spins 3000 RPM , at below tranny options valve counts.
54/59mph (104km/hr = 59) 5sp MT.
64.6 4sp A/T (goes fastest due to more aggressive OD + axle ratio is lower.)
56/.53 2sp A/T
see how drive line effects RPM? so will your cars options.

in the engine bay above the battery from memory is the fuse box for the main fuses & relays they should be marked on top of case one is for the fule pump.

hi

Is there a leak in one of the fuel lines? Check the length of the fuel lines from the pump (you may need an extendable mirror to see the top of gas tank) right up to the point where it enters the fuel rail on the engine. Take special note of the junctions and try to do it with the car running and at a slight idle so fuel is pumping. Check next for a smell of too much gasoline along the fuel rail as one of the injectors may be improperly seated and or broken and leaking. Has the service engine check engine light come on at all or come on and gone out. If your o2 sensor(s) go you use more fuel. If they go there should be a code stored in your PCM (computer). You can pull any codes out of that car by finding the connector and jumping it. Also if your air element(filter) or any pipes are clogged in that system up to the throttle body you will use much more fuel.
Let me know how these tests go
SOURCE: 1994 1.6L Suzuki Sidekick has excessive fuel
It could be if it is equipped with fuel injection. There would be oxygen sensors that are getting some strange readings that would effect fuel mixture. i`m not sure if a `94 would have them but would be easy to look and see.
