i just bought a 1994 mark 8, the story on the car is the guys son rear ended some one but the car isnt that bad, it had a over heating problem so the guy had a new water pump, fan, and stat put on. in this process the car started to run ruff and have no power. im guessing it has a cracked head or the head gaskets blown. is there any other DOHC head that will work with the 4.6 thats in the mark? iv been told the head gaskets for the motor are $400 plus? and if you have motor work done the dealer has to reprogram it? and the air system has leaks but the rear end will be down and after you drive it turn it on and off a few times it comes up? and where is the air ride turn off switch? The car has 140XXX miles and it got it for $350 im quessing it was a good deal but its starting to look like hell. Sorry about the questions Thanks Matt

Welcome!
First, check the cooling system has no trapped air bubbles.
Cooling System--Filling
NOTE:
A 50/50 mixture of Premium Cooling System Fluid E2FZ-19549-AA (ESE-M97B44-A and ESE-M97B43-A) of equivalent and water is required to prevent damage to the cooling system.
1. Check all hose clamps for proper tightness. Ensure radiator draincock is closed.
2. Place heater temperature selector in maximum heat position.
3. Remove pressure cap from cooling system reservoir and fill plug from engine crossover tube.
CAUTION:
Do not fill cooling system through reservoir only. Coolant will not enter engine. Only reservoir and radiator will be filled and engine overheating will occur.
4. Add coolant into fill neck on engine crossover tube until coolant reaches top of fill neck on cooling system reservoir.
5. Reinstall cooling system pressure cap to reservoir.
6. Continue to fill cooling system at engine crossover fill neck until full.
7. Start engine, run at idle. Add coolant at engine crossover tube until full.
8. Reinstall engine crossover tube full plug.
CAUTION:
If engine temperature gauge does not move, coolant level is low in engine and must be filled. Stop engine, allow to cool and fill cooling system as outlined.
WARNING:
TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE ENGINE WITH HOOD OPEN UNTIL FAN HAS BEEN FIRST EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.
9. Run engine until thermostat opens (coolant flowing through radiator lower hose becomes hot).
10. Stop engine and add coolant to engine crossover tube fill neck until cooling system is full. Reinstall fill plug.
11. Repeat fill procedure if necessary.
You can have the cooling system checked for the presence hydrocarbons in the coolant if you suspect bad heads or headgaskets.
You can change the DOHC heads to later model years, but it will require a change of the intake as well as other parts.
Check the FAQ for air suspension common issues. The air ride switch should be behind a small door on the drivers side of the trunk lining.
