We sold a customer a 5.4l engine and he installed it and it idles just fine, but falls on its face when put under load. Truck is a 2001 f150 and is not around here. Cus gave me these codes:
P0135
P1130
P0174
P0308
P0351
P0352
P1131
From all I have found, it appears to be a lean condition and cop #1 and #2.
Has anyone had all of these codes pop up all at once after r&r ing an engine? I have searched for all of them at once, and that was no help.
I am thinking bad intake gasket and possibly bad coils.
Thanx

 

You have an interesting list of codes.
Here is how to go about solving.
Look at all the code discriptions and wright them down.
Look at the overall suggestive nature of them.
130/135 involve ox sensor 1 bank 1.
308 is cylinder 8 missfire.
351 is the coil primary open on cylinder 1.
174/1132 are likley simpathy codes in reaction to the faults.
.
All this seems to suggest there is a large harness issue at some point back near the computer since the problems are showing up in various locations and fuses may be blown.
Questions;
Was there any work done?
Was the truck taken off road?
Etc.
Don't dismiss there being more than one trouble at the same time.
Take a good look from this point of view and don't drive the truck with those two cylinder out because you can lose the Cats from the Raw gas being passed to the Cats and lighting off to very high temps if that has not already happened.
Good luck. Let us know what you find.

 

He did just swap out the engine, is it possible he took out the main harness in the r&r?

 

We ran the engine here for him and it ran fine in the donor truck, I just cant seem to figure out what his issue is as it seems random to me.

 

Engine work is the answer.
The issue just has to be found.
Good luck.

 

Just saw a guy do an engine swap . The upper intake was cracked , switched , crap in ports . TOAST ! Next ...Looks electrical , Maybe ? I pulled a mixer out of a chevy last month Towed from another shop , wiring harness pinched between the block and bellhousing !Fixed it , now engine runs properly .
