Hi,
I saw that you got a new Tiger Racing hood. Are you considering selling the CF one you had the cracking issue with? I'm local to LA, and pretty sure I met you once at Mustang Country.
Thanks!
Hi everyone,
Reviving this thread with an update for everyone. The car was fixed in Dec 2016, and the problem ended up being exactly what I feared from the beginning; fried PCM.
I ordered a reman one from Flagship One since they come loaded with the stock tune and have a lifetime warranty...
Fantastic post, thank you for taking the time to write this up so clearly.
I've already done the first test and confirmed 12V in the harness, so I guess I'll be trying the second this weekend. Hopefully, it yields something- and doesn't reset the PCM again :disgust:
UPDATE:
Low, weak idle problem solved, and most of the weak running situation cleared up
I started questioning whether I had reset the ECU properly, so I went through the steps very by the letter
1. Reflash the tune to stock
2. Disconnect negative terminal of battery for at least 30...
Confirmed no exhaust leaks (stock manifolds and h-pipe)
I have not tested temp via a thermal gun yet, but I'm not sure what that would tell me other than one bank might be leaner than the other.
FWIW, the live data shows the cat temp via the sensors is within spec
Good video, but that's just for testing the O2 itself. I've used three different O2 sensors (OEM Ford, 2 NTK) all of which threw the same code almost immediately. The problem has to be on the car side
i have confirmed the sensors are getting voltage and the ECU is receiving voltage switching...
Yes, I feel PCM is the last result as well, and I don't really feel that is the source of the problem; I'm just put of ideas and so is everyone I have spoken to, including technicians.
I can't find any obvious wiring problems, and all fuses and relays have tested as good.
Checked the harness...
Bump, because I still need help and trying to avoid a major shop expense :(
So far all indications are pointing to the PCM, but there is still only one code and all systems functioning, and car is technically drivable, but it's very weak and running rich.
Does that sound like a possible...
I did confirm fuel and fire by pulling the COPs & injectors one at a time while the car was running
That was my thought, but I don't know what it where the issue could be. So far the wiring looks totally fine. I will be tracing it more this weekend to see if something is hidden
Hey guys, still the same, possiblly getting worse
I did check fuse #47 (as well as all other underhood fuses) and it's fine.
MAF is not dirty
Harness shows no visible burns or damage
Used an Innova handheld to pull codes and run live data. Still gets p0155 instantly after clearing...
They only fit because I went with the offset strut option on my CorteX Racing suspension. I've run as big as 315/30/18 front/rear on track with no problem.
Hoping someone here knows where I can begin to track down this problem as Googling and forum searching has not revealed any answers.

Problem: Constant p0155 code
