Stratus 97 spends a lot of gasoline

I ask for your help. My Stratus Model 97 spends a lot of gasoline someone told me that it is a sensor that is damaged but I do not know what it is I hope someone

also advises me to have a fault when starting the first 200 meters Tironea does not enter the 2nd speed, or if it heats it for a while before starting, the failure is passed but after heating it a good time. a mechanic ke the transmission told me it is not Porke already took him to Rreglars it ... please someone who can help me

Check the air filter, the air flow sensor, the MAF, also check if it has a disconnected air tube, it can also be the EGR valve or the Lambda probe.-

Thank you very much for your answer. I was very helpful!
I checked it and if I had air leaks, 2 burst hoses. Take it to the mechanic and that was corrected. The bad thing is that a tironea and takes to enter the 2nd 1eros 200 meters that I turn it down. Could you suggest something else?
NB still spends a lot of gasoline, but I haven't tuned it, could that be? Or is there really a sensor that fails the Stratus and makes them spend more?

THANK YOU SO MUCH!!

Hello you take

with respect to the fuel consumption, the tuning is not very important when it was the last time you did it but reveal every 6 months or 10,000 km. Since if the filters are very dirty or the spark plugs have already given their better the computer or switchboard attempts to recover the power by increasing the delivery of fuel. On the other hand, the transmission could also need an oil change.

Hello, the Check light is turned on by chance if so, you must control the computer, if not after having made the tuning you should lower the fuel consumption, rewavian the cable of the overwhelon that goes to the change is possibly drawn and is too tense and when accelerating it remains in a tension and does not let the change make, when you make the tuning, the tuning acceleration, I greet you Alfredo.-
