PO-430 Catalyst System Efficiency Below Threshold (Bank 2)
PO-0301 Should be a misfire on COP Coil #1
PO-316 Misfire Occured in the First 1000 Engine Revolutions
P-2195 Lack of HO2-11 Switch/Lean
P2197 Lack of HO2-21
I have the same vehicle,only a V8
What you have is a very common ford problem. The Ignition Coil on Cylinder #1 is Bad. You can buy it at the local auto part store and change yourself. About $59.00. You remove the coil cover on top of the valve covers,then the coil. I did one in Feb and believe all you need is a 7mm wrench and 7mm socket. #1 should be at the front of engine/pass side.
The other codes are related and you can see if any are there,after you do the coil replacement. If so give them to me.

P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
weak coil pack
fowling spark plugs/wires
Low fuel pressure

SOURCE: Missing, running very rough at
the P0011 and P0022 are the camshaft sensors (both sides) are over advanced--common problem on Fords, and is usually a defective VCT solenoid (variable cam timing solenoid)-it will cause your other codes (P0300 random misfire), P0305 (#5 cylinder), P0307 (#7), P0316 (misfire at startup)-P0171 is a lean condition on side 1, where #1 plug is located (look for a vacuum leak, but a faulty VCT could also cause this)-is there any chance the last oil change set this off? The proper viscosity is very important and may have caused these codes.
The P2198 is O2 sensor signal stuck rich bank 2 sensor 1. Has the engine or sensors recently gotten a bath in oil (seafoam?)-this code indicates something of possibly an over zealous maintenance procedure could have damaged maybe the MAP sensor, or more.... Unfortunately, you have a lot of company. At least you didn't crack a piston or hydrolock the engine. Seafoam is pale oil, naptha, and alcohol. With more detail there should be a reason for all those somewhat related codes-post more information.

Hello, There is an extended Warranty for "Cam Phasers". I want to say 7 Years and 90,000 Miles. But some of the repairs are on a case by case basis. Years 2004-2008 were affected.
I will tell you what your Codes mean.p0011 and p0022 are both for the Camshaft position sensors. One side is overadvanced and the other is retarded. Code p 0171 is an O2 sensor, Code 0300 is random misfiring, Codes p0305 and 0307 are the #5 and #7 cylinder misfires. Code p0316 is a general misfire when starting up, and finally the p2198 is a rich condition O2 sensor on bank2 sensor 1.
All of these make sense when the Cam on bank 1 is over advanced you will run lean and the Cam on bank 2 is retarded, you will run rich. The misfires are from incorrect timing and affected fuel mix.
There are "cheater tools" for this repair which will cut Labor costs in half. Check the Web for Mac tools, Snap-on, and so forth. The cheater works by pressing down on the internal chain tensioner to make slack in the timing chain. You take off the valve covers and unbolt the Cam (Phaser) gear and sneak it out through the valve cover opening. The CAM PHASERS cost $300 to $500 apiece.
A normal repair without the cheater involves removing the front of the motor up to the heads and still requires removing the valve covers.
I hope my solution is very helpful to you, at least you know why you are getting the Codes you are reading.

2004 Marauder and 2003-2004 Mustang vehicles built before 12/19/2004 equipped with 4.6L 4V/5.4 4V engine may exhibit a runs rough, lacks power, and engine misfire, prompted by a MIL light and DTC codes P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, and P0316.
Diagnose engine for engine misfire concern. If diagnostics determine an engine misfire which is characterized by leakage through exhaust valve(s), only replace the affected cylinder head(s).
SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8.
