95 taurus 3.8 idle low after warm up - 1999 Ford Taurus

first thing to check is your coolant level, top up if low, this is probably the biggest reason for low to no heat. Press the helpful button.

NEEDS FINE TUNING MATE, THE AUTOMATIC CHOKE COMES O WHEN YOU FIRST START UP THEN SHUTS DOWN WHEN THE CAR IS WARM, JUST UP THE IDLING SCREW A TICK THAT SHOULD SORT IT OUT COBBER

The idling setting in the car is not set correctly or the idling is LOW due to fault in the setting.
You will need to check if the throttle position is correct and the idle setting WITH THE CLUTCH PRESSED must be of the CORRECT IDLING RPM. If not reset the position after cleaning the system.

try new sensors they do go bad after a while

hi if it is an automatic transmission, it actually has to be idling to fill, if not you will not put enough in...hope this helps

the systemis trying ot protece ieself for 2 reasons you have high pressure or low pressure with what you have told us here that you have low pressure which in turn means that you are low on freon or high/low pressure swich is bad ... which i doubt very seriously but it can happen id go back with the basics and start from there, Ithink that you are low on freon,thanks and I hope that this helps you.

95 monte carlo is idling high we just replaced the intake manifold gasket. How do I fix this and could I have caused it.

idle is set to low..adjust idle when motor is warm (not in choke mode)

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.

Usually the sign of low water level in the radiator. The first thing to be starved of hot water when level is low is the heater. When you rev engine up this speed up quantity of flow and so some gets around the heater. Check level in radiator as well as header tank. Top up with the correct coolant.
