Failure in Mustang 2002

Hello, how are you? I just registered and I need your help, I have problems with my car, it is a 2002 GT 4.6 Mustang, the problem is that it is consuming me a lot Sensors I change them but I feel the same, could anyone orient what could it be?

Aver 500 rpm is almost normal, to a greater displacement less number of revolutions in Relay, this is the thing, not the setback as many people think, the consumption of fuel for a vehicle 4.6 is vastating high even with the vehicle in perfect condition, when you feel it the same are you talking about that it goes down a lot?, your musnang brings distributor? If so, you could advance it a bit just a little so that it does not tend to go out.

K Tal Mira There are 2 things 1 ... the sensors that mark you can be because there is no synchrony between the time chains (it brings 2) they are probably loose or the worn guides and that can make you out that the car is destabilized and therefore wants to go out ... if they are not well synchronized, it produces you demonstrate spending in gasoline
2 ... I do not know how often you maintain your car ... The minimal march ... when it gets dirty also tends to quench itself but by this detyalle it does not consume so much gasoline ...... I think your problem is that the chains are very worn ... those cars do not use a distributor ....

Hello, thank you very much for taking the time to respond, affectively does not bring a distributor, in terms of maintenance I have made them punctual, I have little a year with the car, and your way if they are the yields because it already begins to make a strange noise as of hitting or drag, now my question is, what is so expensive is to make this change of chains?

Well, here in Tijuana you will spend like 3000 pesos
