MAF? It should be 40 bucks or so :wink:
For a 2005 4.6L, an Mass Air Flow sensor goes for $50 USD online and $120 USD at the local parts store.
I tried testing it via
these instructions, and it seemed to pass. However, a more
detailed article advocates (basically) replacing the PCV before testing the MAF. He gives 2 rules before begining the test.
- make sure there's no vacuum leaks.
- " Verify that the manufacturer-speci-
fied PCV valve is correctly installed and
functioning as designed. (This is one in-
stance where precautionary replace-
ment may be cost-justified."
So, in order to test the MAF further, I need to replace the PCV first, which on this car is more expensive than usual because it has a heater. To just guess-replace MAF, I need to replace both the MAF and PCV. And if it were my car, I probably do that just to eliminate them as a possibility. But it's not my car, and from a non-technical environment, guess-replacing presents some problems.
I'd have to explain to my old housemate that we need to
experimentally replace these parts. He won't understand and will expect the car to run afterwards. This has already happened in a sense. Thus, regarding that sensor, I'm sort of stalled in the project.
Besides, I'm not getting any codes pointing to the MAF. The engine isn't giving any codes at all now.
But I'm now ambivalent regarding continued repairing of this car. On the one hand, I've invested
so much time, I'd like to see the project through. Honestly, that's the real reason I want it running now. If I had any obligation to my housemate, I've way over paid already. (This isn't the only think I've done for him, I should add.)
But on the other hand, spending time on this car has caused serious neglects in my own life. I really need to spend my time doing things that will improve my own (+ wife & gone kids) condition. I'm behind on everything, including my little business. Doing few-hour repair jobs for my housemate was acceptable. But working day after day to restore a junk car (polished on the outside, though) is really a waste. And even if I get this car going, it will probably fall apart for some new failure soon. (The air-suspension is about to die for one thing.) It's a poorly-maintained car with 280,000 miles (450,000 km) on it. That's more than the distance to the moon.
And, btw, I just learned I should correct a previous statement that relied on what my housemate had said. He didn't pay $1,000 + his previous car. The truth is it was $1,800 + his previous car. Basically, someone talked him out of his car.
Today, I began to realize that my housemate getting scammed is one thing, but I'm compounding the scam by being sucker #2. At this point, I'm the real victim here, and I didn't even realize it.
So today (after 4+ months of devoting all my available time to this), I began the process of - figuratively - getting out from under this car. I tried to explain the tech situation, and then I told my housemate he needs a different car. He got angry and upset, and to justify his anger, he even recounted some events differently from the way they had happened. He doesn't want to own responsibility for the problem.
Although he won't directly say as much, he holds
me at fault for this car not running.
But I never drove it before it died, he didn't consulted me before buying it, and I'm not getting paid anything for working on it.
It's a symptom of senility to use irritation and irrational fact-changing as a defense. You've heard of "crabby old person"?
So this thread may end unfulfilled. Maybe I'll stop working on it (but perhaps it's a pity; maybe all it now needs at this stage is a MAF sensor).

I have had to diagnoise my cars first hand before letting them go to the mechanics because they an't find no fault codes or anything so better of giving them the answer and the parts so they can repair and change the parts for their hourly fee.
Crank sensor is kind of a abs sensor but its located at the crank and it can start if its in the right starting position at the start but wont start if its the position is wrong and the sensor is bad.
And old perfecly serviced car is way better than a heap of unknown unknown uknown. That old man traded down.
