Loss of power, but no mention of rough or inability to idle (including stalling). If those additional symptoms are part of the problem, check for a vacuum leak to the intake. Listen for hissing or sucking noises near air hoses. Look for loose, cracked, or broken air hose connections. Check PCV valve...Cheap to replace, could be sticking, then loosen after truck sitting with engine off. A vacuum leak will not give any light indications, and vehicle will seem to run normal when applying gas, but will want to stall or run rough (or want to stall) when at idle or sometimes when taking foot off gas when slowing down.
EGR struck open. compression low and 1 or more cylinders. ISC parts sticking, id CEL lamp out driving or idling no, scan it. if in canada, scan it 1 more time.
Check when idling and warmed up if the rev drops when the AC is on. It may be too low or is running rough. You may have to adjust the idle screw with little adjustments. If the idle is running rough, inspect the idle air control valve. It may be dirty or faulty.
IDLE AIR CONTROL VALVE IDLE SPEED TOO LOW. IDLE SPEED SHOULD BE 750 - 850 RPM. IDLE SPEED NEED TO BE CORRECT OR IT WILL CAUSE ENGINE RUN ROUGH OR STALL OUT.AC COMPRESSOR WILL TAKE SOME POWER FROM ENGINE WHEN AC IS OPERATING.
2003 Ford Windstar-this may the idleing amount is too much so which may makes it to idle rough. that means too much of fuel going inside the engine.
Engine stalls- this is because the when the car is off and when AC is on the AC runs in battery. When you try starting the car the starter motor takes power from the battery. it doesnt have enough battery power t o starts thats why it stalls.
I have a durango R/T 5.9, but with any car you buy especially like one's with big block V8 any time you turn on the ac your vehicle will lose power as well as consume more fuel hence you vehicle has to idle at a higher RPM.
