Engine Problems, Need some Help?

Not sure what you considered a safe air fuel ratio. My professional opinion, tells me by the look of those plugs, you are rich. sub 12.0 rich. now this can be for several reasons. Tunes don't just change, something changes them. I would look at your intake temp sensor, water temp sensor, and check for an air leak or a maf issue. If there is an air leak between the maf and o2 sensors it will run like shit.

Ok, started it up and let it run for a bit. Even after warmed up it continued smoking from the exhaust, more from the passenger side than the driver.

Also, on the passenger side exhaust manifold to the engine I could see smoke coming from somewhere around it and smell a light burning as well?? Nothing from the driver side manifold.

Here's some pics of the tailpipes, you can see a difference in moisture:

the carbon in your tail pipes is the same carbon on your plugs and in your oil. All tall tail signs of a fuel washed motor. Bet there is a gallon of fuel in the crank case too.

What about the smoke for the exhaust manifold?

My car is now throwing the following 2 codes:

U1900
U2011

This is so fucking annoying!

My car is now throwing the following 2 codes:

U1900-Too much supercharger
U2011-Too much boost

Rich is Wrong

What about the smoke for the exhaust manifold?

When the cross hatching on the cylinder walls gets scrubbed off by excessive fuel wash in the cylinder, the rings get over heated, loose their face value and tension, you loose ring seal. the oil looses its viscosity from excessive fuel being hydraulicly forced past the piston and rings into the crankcase. you got rings that can no longer control the oil on the cylinder wall. wet fuel is not compressible, no matter how much timing you throw at it...if it's wet, it's not going to burn. Just makes excessive cylinder pressure, and forcing the egt's threw the roof. Pressure is heat, and heat is pressure. The raw fuel has got to go some where. what doesn't go out the pipe or revert and saturate the intake charge, get's hydraulically forced into the crank case.

My apologies I should have said "locked"

I believe you are right, I checked the oil dipstick and it does smell a bit like fuel. Definitely doesn't smell just like oil.

Should I change the oil before doing anymore to it?

I know on '03-04 Cobras when the FRPS goes bad you get an extreme rich condition like that. Not sure if 3V's have the same type of setup, but you might look into that. Sometimes when it blows the car won't even start but others have reported that theirs still ran but had rough idle and hard starting.

First thing you gotta do is look at it.

I looked a bit online and see that has caused many issues. Many said after letting it idle for a few mins to turn it off and smell the vacuum line from it for gas, but mine didn't smell like fuel actually smelled sweet?

I just don't know what to do, prior to replacing the fuel filter, sparks plugs, and compression test it drove ok but now the idle is way worse very rough. Don't even think it would drive if I tried!


Guess I'll have to get it towed to a Ford place, I need my car Anyone have a Ford Service they'd recommend??

I would try replacing the frps, I have had those go bad and they do make your car run like ass. I always changed the oil after replacing one of those because it dumped to much fuel into the cylinders. Also mine never smelt like gas but it is what was wrong. I went throw 3 of those before I had the tune redone on my old mustang.

I had an FRPS go bad on my '03 Cobra motor too. Oil reeked of gas.
I think if it's bad you will see big fuel pressure spikes when you rev it, so if you can datalog the fuel pressure you might be able to tell if that's the problem.
