Unfortunately sounds like blow-by my friend or a messed up PCV valve. Three options; A. REPLACE THE PCV VALVE and hope that it was just defective

B. REMOVE THE HOSE FROM THE INTAKE and reroute it so that it blows else where like down out under the car
C. USE HEAVIER OIL in hopes that it slows down the amount of blow-by

Either way a compression test on each cylinder should be done to located the primary issue

Where is the air charge temp control sensor located on a 1999 ford explorer 4.0 sohc

Generally the Air charge temp sensor is in the intake tube between the air box & the intake. However, there is a possibility that it is part of the Mass air flow sensor.

I have a 1996 dodge stratus that was stalling when you would come to a stop, I was getting a IAT sensor code, I unplugged some of the connectors under the hood to check for corrosion, everything looke

If the mass air sensor (MAS) is malfunctioning, it could be telling the control unit that a lot more air is entering the engine than the true amount of air. So more gas is distributed to the engine to match the mass air reading. When you unplug the PVC from the hose, you are introducing more air and are one step closer to equaling what the possibly malfunctioning MAS is telling the control unit. Connect all hoses and sensors. Disconnect the MAS. It will be that sensor, just after the air filter. This will put the MAS readings into fail-safe (general parameters) . If this MAS is reading incorrectly, the engine should be smooth when the MAS is unplugged. If this fixes your issue, there is special cleaner to spray and clean the sensor. It may not be bad. It may just have a coating on it (inside the air intake tube). I've seen a feather on the mass air sensor shut down an engine completely

Where is the iatsensor in a 2000 ford explorerwith a 40 sohc engine repair book says it is in the intake tube but i is not . where else should i look for it and what does it look like

IAT sensor ( Intake Air Temperature sensor) is in the air intake tubing by the air cleaner. It is about the size of a spark plug and has 2 or 3 wires plugging into it. Just look for wires going into rubber intake tubing and you found it. Hope this helps.

My 1990 Honda Accord had a leak into the spark plug area, and also the tube between the pcv and recycled air intake was collapsed shut. I replaced the head gasket and tube. now i'm getting blow by (oil...

The pvc valve will always let some oil out into the intake to burn. That's normal. Now for the misfire at 2000 rpms, I believe you will have to clean out the EGR passages on your intake system. Basically, three of the four individual EGR passages are blocked up and when the EGR opens, it floods only one cylinder with exhaust gas, causing an extremely lean condition and misfire. It's not an easy task to do on that year Accord, but I think it's what's causing the misfire at high rpms, when the EGR valve opens.

Has bad hesatation when tacking off like its not geting fuel

Try unplugging the mas air flow sensor.This is located in the air duct that goes from the air filter to the throttle body.If it takes off normal when unplugged then get some mass air flow sensor cleaner and remove and clean the sensor and let it air dry.You can find cleaner at most part stores.This should take care of your problem.Let me know.Good luck.
