Check Throttle position sensor again. If you unloosen it the one hole is slightly slotted you have to be within .9 volts if i remember right. start the car unloose the TPS and slightly turn or move sensor to adjust idle you will here the engine go up or down depending which way you move it. 5.0 should idle at 500 rpms. And make sure you don't mess with the idle plate screw if you did this will throw the TPS off. (Just reset the idle plate screw if you did turn it.)

Try taking pff your throttle body and cleaning it and also check and see if your throttle cable is tight or try loosening it and see if the throttle drops. Could also be a bad o2 sensor staying in open circut

Double check and make sure you have enough coolant in your system. Additionally why you are at it put in a new thermostat preferably the lowest temp allowable by manufactorer. A cool running engine is an efficent engine

Not a problem just a question...


The cheapest would be a cold air kit (probably less than $200.00). It is easy to install, but won't quite get you there. The next is a better exhaust system (probably under $200.00). The other easiest modification is a performance chip or engine tuner, but they can be upwards of $300.00. A high performance coil, spark plugs & wires can help as well. The bad news is that each of these will make a minimal improvement by themself. Together they make a grand improvement. Everything is expensive.

2008 ford expedition air conditioning problems


the ac pressure depends on the gas in use
r314 runs at high pressures
overheating at slow speeds indicate an inefficient coolant fan and the high ac pressures indicate that the condenser fan also is not operational
if it has a viscous fan hub , replace the fan hub
if it has electric fans check / the fans, fan relay , fuses , coolant temp sensor

2001 mustang...6 cylinder. Car overheats at slow driving speeds with ac on. Temp goes to the H on temp guage, but not over redline but almost. Electric fan running. Ford dealer flushed radiator and changed...


Check that the water pump drive belt is tight
Check that the cylinder head is not blowing.
Check the impleor on the water pump is not eroded
Check theair flow through the radiator is ok.
Check electric cooling fans operates if fitted.
Are you driving in to low a gear?
Are the brakes draging?
Check to see if you have some contaninated fuel
Check that the correct ignition time is ocurring at all engine speeds.

My Ford Mustang 2002 Idles high at start up. Why does it do that? It even idles high in gear when i am not pressing the gas and the idling is causing it to speed up more on its own when Im not pressing...


Hello and welcome to FixYa!

All EFI (electronic fuel injection) engines idles high during start ups. It serves like an auto choke to regulate the vacuum supply and most of all to lessen the wear and tear of the engine. Please drive the car only when it reaches the normal operating temp.

Hope this helps and thank you for using FixYa! Have a good one!
