The major problem with fitting different engines is the transmission housing compatibility
if the bolt pattern is different, the cost of obtaining an adaptor plate makes the different engine fitment expensive
there is a technical division in ford motor company that you can contact for advice and they will be able to advise which engines have the same bolt patterns that will allow the change over
of course the other method is to change the engine / transmission as an assembly so if you want to put a inline six in use the inline six transmission as well

SOURCE: I have a 2001 ford f150 4x4 .6 triton misfiring

The way that I usually test coils or plug wires is to use an insulated plug wire puller and pull each plug wire (one at a time) to see if the engine speed changes. If you disconnect one wire and nothing changes, you probably have found the defective wire or coil.
You can also use a plug wire tester (neon type) to see if you have a spark. Can also hook up a timing light to a coil wire and it will trigger if coil is good. It will not work if coil is bad.

SOURCE: Keeps throwing the belt off

I had the exact same problem, except it was shredding the belt as well. It even jumped off the pully after just distance down the road. Come to find out the idler (which had been changed out with what was "supposed" to be the right one) was the wrong one. It looked right, but after changing the idler out we have not had this problem again.

What engine code is stored in the computer? You may have a bad TPS (throttle postioning sensor), or a bad O2 sensor. Auto Zone can retrieve the code for you, and tell you what sensor it is related to.

What engine could i put in my 03 f150 other than a 5.4L triton cause I've bought two and I'm not going for three .all I've heard is only 5.4L ....just can't believe it.


According to this page, If you have the 4R100 transmission then your only replacement while keeping the trans is the 5.4L.
If you have the 4R70W then you can also use the 4.3L V6 and the 4.6L Triton V8. You may have to change computer transmission shift points but between the two Tritons it probably doesn't make much difference.

Yes. You need the ecu that came with that engine. Did you switch intakes? The f 150 4.6 has a taller intake and I believe the stroke is different. I would switch the throttle position sensor too.

Location of the IAC value on a 2004 Ford F150 XLT pickup with an 8 cylinder Triton engine


The New Body Style 5.4 does not have an IAC, this is controlled by the throttle position motor on the side of the throttle body, and is operated by the PCM ( new body style is throttle by wire ).

If this is a 2004 Heritage or lightning ( the same body style as the 97-03 MY ) the IAC is on the back the throttle body, held on with 2 8mm screws. You would need to remove the plastic throttle body cover to get to it.
