Ford Explorer 95 4.0 Check Gages and Cataliza Light

Friends that I went to see a 1995 Explorer XLT to buy it and have the light on:

Check Gages
Catalizer

was almost no gasoline, as data, the alternator load was optimal, the pressure of normal oil and the temperature little climbed, the rest good ... If someone has experience can guide me, the tank must change it? or can it be cleaned ?? I beg you to help me before closing treatment with the owner --- Greetings to all and thanks in advance.

Greetings, Check Gauges is the indicator light that warns you that any of the instruments is not working, an eye does not literally mean that any mechanical part is not working.

In the case of the catalyst, friend is not cleaned, the is located in the exhaust or multiple exhaust pipe according to the only way is to replace said catalyst in some cases eliminate them if they do not get the original or exact piece .. those who do is replace it with a lower quality or simolemte change it by a silencer and ready everything depends on the case why if your oxygen sensor is there.

But does one have to do with the other ??? And check gauge can it light when it is with little fuel? Thanks

Not with the fuel drop but you talk to me about
Check Gages
Catalyst

are now 2 different lights ??? I mean the light of
Check Gages
and another catalyst light,

is what do you want to tell me ????

Yes ... that's
