Cold starts have been a bane all winter. When starting cold it idles a bit rough, sounds like a miss. If I try to drive it, I get very little to no power and thick black smoke from the tailpipe and I can hear it missing very good. When I stop trying and press the brake the engine sounds like its choking. When I finally get her going and I get to about 20 to 40 mpg it starts jumping and and loosing speed and power (no smoke though). After she reaches normal operating temps all issues seem to go away. Also I'm showing no codes what so ever.

What I've done (or wasted money doing) so far:
-Cleaned EGR
-Changed GPCM
-Changed Glow Plugs + Harness (I broke it!)
-Changed ICP
-Checked Oil
-Checked Fuel
-Tested the FICM voltage (48 KOEO, 47.8 Cranking, 48 EO) Perfect!

When I changed the ICP it got better but still not good. I changed my oil before winter so it should still be ok. I'm not loosing coolant either. I'm going to try the RevX in the oil to see if maybe that will help. Anyone have any ideas what's going on?

 

FICM volts?

 

Just edited that, it was perfect at 48!

 

What weight of oil are you using? And what are you using to scan for codes? The scan gauge isn't a good code reader. Also are you using OEM/racor oil and fuel filters with the OEM oil filter cap and OEM air filter?

 

There have to be codes. What scan device are you using?

 

I'm using Shell Rotella T6 Full Synthetic 5w40, the same thing I've used in her for years. I'm using my Bully Dog Triple Dog to scan it, I used the one from ORielly's yesterday to double check. I'm using all Motorcraft filters!

 

No codes, the only one I got was for the ICP and I changed that. The unusual thing is this problem has been going on for a while and the ICP code came on last week so I changed the sensor. Its a little better after the sensor but still not right.

 

You need to find something with a little more scanning power. Do you have the Torque Shift app on a phone or tablet? The programmers are almost worthless when used as scanning devices.

 

I don't have that app, what does it do?

 

It's a better scanner than the bully dog / insight type scanners, for one. It provides access to parameters monitored by your engine but not shown on your gauges, for another.

One way or the other, I think you need a better scan.

Auto Enginuity is another option, but then it's a couple hundred dollars invested instead of ten for the Torque Pro app. The next step would be Ford software.

 

Sounds like some bad injectors. Change your fuel filters? How'd they look?

 

Filters looked good!

 

Do your ect Eot tft iat1 and iat2 match after a cold soak?

I'm sorry, I don't know what any of that means. Can you tell me what those acronyms are?

 

Spell check kinda screwed me. Ect = coolant temp
Eot = oil temp
Tft = trans fluid temp
Iat1 = intake air temp sensor
Iat2 = intake air temp sensor #2
