99 Ford Explorer

I have a 99 Ford Explorer Sport that is really getting to me. I have this check engin light that comes on. I took it to shop and they told me it might be my cables, fuel injector, or my oxygen sensors. So I went and replaced my cables and did my fuel injector. They cleared the code and I was on my way. I drove about 45 miles and it came on again. So I took it back to the shop and this time it read oxygen sensor, so I replaced three of them. They cleared the code again and I was on my way. This time I drove about 100 miles and it came on again. So I took it back and they told me it might be the last oxygen sensor. But what if I replace the last one and the light comes again. Any suggestions on this situation.

Bring it to a new shop that does diagnosis, not changes parts. Just because a code comes up it does not mean the part in that circuit is bad.

OBDII has separated parts changers from technicians .

But this is the second person I have taken it too. But it keeps cominf up as lean fuel mixture. What should I do? Also I think I'm having problems with some other parts. For instance, when I brake it makes like this loud noise, like a bump. And also when I turn the steering wheel it makes a funny noise to. I heard it might be the bearings. What do you think?

Might want to haul it into the dealership. There, you'll have some recourse in case they do not fix the problem and charge you for it.

Again, OBDII has separated those that know vehicles and diagnosis and those that simply change parts and throw parts at the problem (which doesn't solve a thing).

Have you added any aftermarket air induction products? I would need to know the exact codes and look at it to be sure. Just so you know what to ask next time I will give you some of the basics you can ask your technician. First you need to ask him if itís a hard fault code, that is, a code for a problem that is going on at the present time. Or if itís a memory code he is pulling. Next ask him do to a cylinder isolation performance test (sometimes called an engine balance test). This tells him if all cylinders are performing up to spec and if not witch one or ones is the weak link. Next would be the Jiggle test, this test will tell him if it has a wiring fault, for this test you do not hook up the self test lead, then ďjiggleĒ the suspected sensors/wires to see if you can generate an error code or engine light. And just for the record this is all EEC-III or IV. If he looks at you like you have lost your mind when you ask him about this stuff find a new technician. These are just basic, first line tests and if you problem is more involved your technician is way over his head. I know the Ford dealership is more expensive, but you might end up saving money by not replacing parts that donít need to be replaced.

Sounds like your MAF sensor is dirty. Ford has a Service bulletin out on this.

front end noise

as far as your front end noise and brake noise first usualy on the front end when u are turning the wheels it is usualy the tie rods or balljoints have a front end check done most shops do the checks for free and the parts are easy to replace if u work on cars. the brake noise if coming from the front check your caliper to see if the bolts are tight and see if the pads are shifting up and down. sometimes the hardware for pads break. if noise is coming from the back make sure no hardware came off and check brake adjustment.
