I really need help. I want to buy this 2004 ford f150 4x4 5.4L V8 but its has 140,000 miles on it. Is it worth paying $9000 for ? And if so how many more miles can i get out of it without anything serious breaking. Thanks for reading !

 

Well, I plugged all the parameters you provided into my HP10bii scientific calculator and pressed Enter. It said Err. Something about missing parameters or divided by Zero.


All I can tell you is mine has over 206,000 with factory alternator, water pump, A/C compressor, serpentine belt, PS pump, tranny, engine, phasers, rear gears, U-joints and the list goes on and on. If that one will do the same, looks like it would work out to about 13 cents per mile - a little less than mine given its original $28,900 cost.


Either case has a lot to do with prior and future maintenance.

 

Thanks alot !

 

@Austinheath123, on a more serious note, the OBDII system maintains lots of information besides just trouble codes. If you have access to a scanner, you can easily plug it into the OBDII port and check if there are "PENDING" or "GREY" trouble codes if active DTC's have been cleared by the seller. If trouble codes have been recently reset , you can see that by checking the following PIDs that are available on the 5.4L. I wish I had done this the last used car I bought my wife.


_PID # _______ Acronym ___ Data ___ Description

0100 ________TRIP CNT ___ 1 byte __ - the Number of Completed OBDII Trips. This counter is RESET when the check engine light is reset.

1103 bit 5 ____MIL STATUS _ 1 bit ___ - What the check engine light SHOULD be showing (if it were somehow disabled)

16DC________ CLRWRMUP - _ 2 bytes _ - Number Warm-ups since DTC’s Cleared (different from "Trips" which requires achieving certain speeds and driving conditions)


ALSO you can check "Freeze Frame" data - showing about 20 operating conditions at the instant the last DTC was set.

Good luck.
