check out with your dealer as you might have a recall to fix this problem.
Overheating - Cooling Fans Inoperative - Replace Module Prior To Retailing - Service Action S932
This Service Action Applies to Vehicles That Have Not Been Retailed
The cooling fan module on X-TYPE vehicles may fail under certain circumstances. There are various root causes but the design and quality of the printed circuit board within the cooling fan module are the most significant. The NAND gate used in the circuit is detective causing multiple failure modes, this can result in high engine temperature and overheating due to the cooling fans not operating.
A change has been implemented in production from VIN C91720. On these vehicles a 'Philips' printed circuit board has been used that has a modified voltage spike protection strategy.
To prevent customers from experiencing this issue, install the latest specification cooling fan module on 2002-03 MY X-TYPE vehicles within the above VIN range that have not been retailed.
1. Install new cooling fan module (see Workshop Manual, JTIS CD ROM, section: 303-03, SRO 26.25.38).
Warranty claims should be submitted quoting S932 in place of the warranty fault code together with SRO: 26.25.38 and the relevant part number. This will result in a labor time allowance of 0.8 hours to replace the cooling fan module and payment for the part used. Should the vehicle be brought back into the workshop for this action alone to be undertaken, an additional labor time allowance of 0.1 hours can be claimed quoting SRO: 10.10.10 for drive in/drive out.
Warranty claims should be submitted quoting the information found in the table. This will result in payment of the stated time and, where applicable, parts/miscellaneous expense codes.
The options that allow for drive in/drive out may only be claimed when the vehicle has been brought in to the workshop for this action alone to be undertaken.
The SROs and parts items listed above have been included for information only, there will be no requirement to enter the parts or SROs onto the claim.
NOTE: Always perform a DDW claim search first to determine whether this service action has been performed on this vehicle. The warranty selection under the vehicle inquiry will give a listing of all claims against the vehicle. If this service action number appears in the program code field, do not perform this service action.

Spake pluge could have gone bad, or the Spark Plug wire. Try changing all your plugs and wire and inspect the old one's. The wire could be bad do to time or may have been against the exhaust manifold and brunt. Good luck

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

If I am understanding your post, I believe you do have a levelling
system and it should be near your light switch on the dash. It is
the type of switch that you depress first, it then springs out and
you turn the small knob (just like your instrument panel lights
adjuster next to it.) What you do not have perhaps, if your car is
not fitted with HIDs (high intensity headlamps), is the automatic
levelling system which is a legal requirement when HIDs are fitted
due to the high power of the lights....
if you don't have a self-levelling system then you'll have a manual
system, operated by a knob under the light switch so that you can
adjust to compensate for a heavy load in the rear of the car.

Testimonial: "I did see the little knob on the dash under the headlight switch. i thought it was to dim the dash lights i will check it out and let you know. "

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.
