just like the title says i can buy an 99 5.4 motor but i need to know if its a pi or non pi

 

I forgot to mention that the motor is still in the truck I have the vin # and an# of the driver side valve cover which is 7g896ab any help please

 

Edit.

 

If it is the original engine (should have a metal/aluminum intake manifold) then it is PI. 99+ 5.4L are PI engines in the trucks.
You can find the build/production date on stickers found on the front timing cover or drivers side valve cover. Otherwise, I believe the back of the head should have a PI stamp.

 

I think the f250-f350 got them in 2000 wouldnt swear to that but I read it somewhere (I think) 99 F150's got them for sure..

 

thanks for the info guys it is a 99 f-150 xlt 4x4 5.4 4r70 and it is the origanal motor with 178,000 miles i did hear it run and it sounded good with no rattles but the man said that it starts to run rich after running a while he wants 600 for the engine and 1200 hundred for the whole truck (pretty much complete still)

 

Then it is a PI motor. If there is a rich or lean condition, the pcm should have a fault code to indicate where the issue may be. CEL on? Could be vacuum leak, egr issue, 02 sensors or other things. Either way, if there is a rich condition, it needs to be addressed immediately.
