|RedRiderr13||ok guys, so im still at a loss on this problem. has anyone experienced anything like this. the engine is a 2.0 duratech. the thermostat is new, the waterpump is new. the fans work properly, the fan blades are good. but the car still overheats. down a hill in 5th at 70mph with a light foot, it is fine, but as soon as there is a slight up hill increase, if i add a slight bit more gas to copensate, the tempurature goes up pretty rapidly. the tempurature is fine at idle though, and if i down shift and accelerate the temp goes down conciderably, or all the way back to normal. if anyone has any clue what is going on, please let me know. if yall need a video, i can try and post one too. thanks in advance for your help.|

|RedRiderr13||i havent replaced it yet, but we narrowed down the culprit to the waterpump being faulty.|

|RedRiderr13||fans are working, i can hear them going when its hot. can anyone tell me where the thermostat is exactly? is it inline a hose, or on the water pump area? also a location to the temp sensor would be much apreciated. thanks again.|

Stat in backwards would overheat everywhere and all the time.
OP should first verify whether fans are positively working when car is overheating. Could be fifty other things besides temp sensor.

|sleepyboy||Maybe they put the t-stat in backwards?|

|RedRiderr13||ok, so i changed the MAF sensor, the check engine light is gone now. BUT the car is still doing the whole running hot thing when on the freeway, no what should i look to change out? im thinking the coolent temp sensor,(anyone know where this is??) thanks in advance.|

|RedRiderr13||i guess ill start going thru everything tomoro, starting with maf, i have already searched for vac leaks. thanks again, anyone with any other ideas, please let me know.|

|Squareleft||most common causes are the maf and vacuum leaks.|

A more detailed description with possible causes:
P0171 - System too Lean (Bank 1)
The Adaptive Fuel Strategy continuously monitors fuel delivery hardware. The test fails when the adaptive fuel tables reach a rich calibrated limit.
Possible causes for lean and rich DTCs:
Excessive fuel pressure.
Leaking/contaminated fuel injectors.
Leaking fuel pressure regulator.
Low fuel pressure or running out of fuel.
Vapor recovery system.
Air leaks after the MAF.
Improperly seated engine oil dipstick.
Stuck EGR valve.
Leaking diaphragm or EVR.
Exhaust leaks before or near the HO2Ss.
A SHRTFT-1,2 PID value between -25% to +35% and a LONGFT-1,2 PID value between -35% to +35% is acceptable. Reading beyond these values indicate a failure.
