I have a 2000 4.0sohc 182xxx miles when its cold it idles at 2500rpm then drops under 500 and stalls. It feels like its mising and runs like poop untill it gets up to temp then it idles fine. I think it might be dirty sensors? I bought a can of crc maf cleaner and cleaned the maf what other sensors can i clean/check and where are they located? Or could it be something else? This is my first explorer we've had some good times. Im trying to fix everything on it so it will last. I've done a few tune ups, replaced all roters and 2 calipers, water pump, alternator, and i am doing both upper and lower balljoints this week thanks for your time
 






Search on intake manifold gasket. It's gotten hard and leaky with age.
