I have a 2002 mercury cougar. After the coolant gets to operating temp both my high speed fan and my low speed kick on and stay on for a long period of time sometimes they dont kick off, do i have air in...

It could be you have a faulty radiator fan relay. There could be issues with the thermostat or thermostat housing. The old Cougar thermostat housings weren't built very well and tend to malfunction. Check the by-pass hose from the heater to the intake manifold after the car is warmed up with the heater on to make sure it is hot and coolant is actually passing through. I would just replace the thermostat, relay, and housing and see if that fixes it first. If these things haven't been changed in the last 10 years then they are due for a replacement. Here's a website that has all the parts and good pictures with descriptions:

Every time i turn on my car and it idles, it will periodically sputter. I notice when i turn on the air it will sputter even more. i notice it the most when i first hit the gas pedal and once the RPM reach...

This is caused by a defective idle speed control. When your vehicle has a power demand from any source such as a kick from the a/c compressor, it sends a signal from the throttle position sensor to the computer telling the this idle speed control to ramp the RPMs'. Changing the idle speed control should fix the problem, if not I would change the throttle position sensor.

Engine ****'s during accel. and tranny shutters.

Check the fuel filter. Replace at about 30k. It sounds like low fuel flow. Check air filter as well.

Stalls while at the stop light or stop sign '95 Cougar 4.6L V8

I'd concentrate on idle air control valve. IAC valve. They control engine idle speed.

This may be your problem.

FORD: 1994-96 THUNDERBIRD LINCOLN-MERCURY: 1994-96 COUGAR ISSUE: Steering efforts at low speeds may intermittently increase to the heavier for highway setting on some vehicles. This is due to electrical "noise" from the Vehicle Speed Sensor (VSS) being picked up by the Electronic Variable Orifice (EVO) module. The EVO module then interprets this as an increase in vehicle speed and reduces the steering assistance to the heavier for highway level.
ACTION: Replace the EVO module with a new module that has improved filtering for electrical noise. Refer to the following Service Procedure for details.
SERVICE PROCEDURE Replace EVO module (F6SZ-3F712-BB). Locations are as follows:
  • On 1994-95 vehicles, the EVO module is located under the package tray in the trunk.
  • On 1996 vehicles, the EVO is located under the heater blower case on the passenger side.
Refer to Section 11-02 of the appropriate year Thunderbird/Cougar Service Manual for additional diagnosis and repair information.

WARRANTY STATUS: Eligible Under The Provisions Of Bumper To Bumper Warranty Coverage
OPERATION DESCRIPTION TIME 960402A Replace Electronic Variable Orifice (EVO) Module - 1994-95 Thunderbird/Cougar 0.5 Hr. 960402B Replace Electronic Variable Orifice (EVO) Module - 1996 Thunderbird/Cougar 0.3 Hr.
