IT TAKES ME 15 MINUETS TO GET TO WORK BY THE TIME I GET THERE OR MY CAR IDLES THE TEMPERTURE GAGE GOES UP HALFWAY OR A LITTLE HIGHER,I TURN AC OFF TURN HEATER ON UNTIL TEMP COMES DOWN WHY IS THIS.

It sounds like the oil sending unit is bad. the safest way to check it is to pull out the sending unit and install an oil pressure gage directly to the motor start it up, bring the RPMs up and see what the oil pressure is. Ideally you want at least 15 psi at an idle and prefereably anything above 25 psi at crusing RPM.

Yes it helps the A/C when stoped at a stop light idling . the cooling fan coming on pulls air through the A/C condensor taking away the heat . Before replacing the fan , check to see if it is indeed bad by jumping the socket where the relay plugs into . Pull the the relay an look on the bottom , you will see four sets of numbers 30 &87 plus 85 & 86 . 30 & 87 are the two you want . Take a paper clip or a piece of 12 gage wire an jump 30 to 87 if the fan runs it's OK if not replace it . Just replaced fan on my 05 cavalier last summer .

There is no module under the dash on your vehicle .
P0463 - Fuel Level Sensor A Circuit High Description: The powertrain control module (PCM) monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves above the maximum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank. Possible Causes:

• Fuel pump (FP) module concern
• Incorrectly installed fuel gauge
• Damaged instrument cluster
• FLI shorted to VPWR
• CASE GND circuit open
• Overfilled fuel tank
• Damaged fuel gauge

Diagnostic Aids: See the diagnostic aids for DTC P0460. Application Key On Engine Off Key On Engine Running Continuous Memory Ranger GO to Pinpoint Test HX . All others Refer to the Workshop Manual Section 413-01, Instrument Cluster for fuel level indicator diagnosis.

Hello good sir or mam

So here is goes when you turn on your ac system you put a harder load on you engine as it engages the ac compressor clutch. That being said if you are low on freon your ac compressor will be harder to turn as refrigerant contains oil for your system too.

You may also want to check your serpentine belt as a worn belt will cause this to look for frays,cracks,or a depth Gage. also you may need a tune up check your spark plugs,igniton coil, and or distributor cap & rotor if applicable older models.

You may also need to replace your idle air control valve as it can definatlly cause this

well i hope it helps if so please leave 4 thumbs up

sounds like the gauge and sensor r workin properly....but you do have to address that coolant leak...that causes your temp to fluctuate cuz you cooling capacity is being reduced

If you unplug temp sending unit and turn ignition on check guage. It should read all the way hot or cold. If so then replace temp sending unit.

Hopefully fixed the problem by setting the idle a little higher. I think the IACV is ok.

engine coolant temp. sensor is probly cracked it will cause the idle to race, car may smoke, and at time could be hard to start.. It is about 15 dollars, and it is located on the right side of the head if you are looking at the engine.. pull it out you will be able to see if the tip of the ceramic tip is cracked.

Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.

need to know how to change the fuel pump, do i have to drop the fuel tank or can i get to it from under the back seat
