Run fault codes to find faulty sensors. Then there are dozens of reasons for a thirsty engine so I will list a few
1 tyre size and inflation
2 driver habits
3 blocked exhaust (cat converter faulty)
4ignition timing
5 fuel injectors
6 load in the vehicle
7 load on top of the vehicle
9 speed
10 area= Hilly --city -- stop start
11 if carby check for faulty power valve.
12dragging brakes / pads
13 fuel pressure
14 not engaging OD in automatic box
15 drive line wear
16 wheel alignment
these are just a few and a combination of any will knock considerable mileage off the economy.

If it has a caby then check why the float is not controlling the needle and seat that controls the amount of fuel into the carby. Check the needle and seat for something like a hair or the rubber on the needle is cracked or the seat is loose in the carby body. Concentrate on the carby as the over fuelling problem is in that area. Check that the choke is not coming on

P 0402


Hi, P0402 code means that OBD detected an excessive amount of EGR.
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc.
With a P0402, it is common for people to replace the EGR valve, only to have the problem return. The most likely solution is to replace the DPFE sensor.

The car does not rev higher then 3000 RPMs, it uses an excessive amount of gas,I have installed a used computer from a 1995 accord, could this be the problem?


It could be the problem, but i would do some more checking before saying its the computer.

It sounds like you have a plugged exhaust to me.

Hyundai coupe excessive fuel consumption


Unless the Check Engine Light is ON, there is no vehicle-related issue to fuel consumption. The computer will deliver the exact amount of fuel needed to satisfy the demands placed on the engine, using input from a large variety of sensors, including the accelerator pedal position sensor. Fuel economy estimates in the USA are just that, estimates, derived from a chemical analysis of emissions, and not actual driving. And no vehicle ever hits those numbers.

There are numerous outside factors that have a negative impact on fuel economy:
Vehicle maintenance, driving conditions (stop & go driving KILLS fuel economy), accelerator pedal usage, overall vehicle speeds, loads carried, etc.

Remember, the more you use the gas pedal, the more you use the gas station!
