1997 f250 7.5 engine idle problem
Got 1997 f-250 7.5 gas truck tried to do research on this problem but cant find the truck or engine anywhere that i am having. When i hit the gas and let it go the engine will go to very low idle or will stall out. At normal idle it almost whats to jump out of the truck. please help me out i am racking my brain over it for a long time. Thank you

Start by checking the IAB and its circuits,
Ford Fuel Injection » Idle Air Bypass (IAB)
The computer uses it to control idle speed, often just need to remove it and flush out the valving end with carb cleaner. Hold the solenoid end "up" while flushing the business end to keep dirty cleaner from contaminating the electrical end of it.
The valve should move freely and should be free of any carbon build up that might be causing it to stick.
