Hi there just joined but straight to business I bought a celica st202 last month and been driving it around noticing how much fuel it uses now I know it's a 2.0 litre so it's never gonna b an Eco car but it's 295 pounds of fuel in it in 3 weeks and on rough calculations it's doing 8 or 9 miles to the gallon and that's driving it like an old man, also when u start it from cold it revs to 2500 rpm and takes over 10 mins to come down to 900 rpm and stinks if fuel all the time . I have checked the plugs and leads there all good checked for fuel leaks there are none but possibly another symptom is
