Car keeps running hot. Have added coolant several times. VIN# 2G1WF2E519264894

You have to verify if you have residue from coolant near the EGR below the composite air intake. If you are adding coolant and the car engine still have power then your coolant is vaporizing out and not in into the engine block. Otherwise if the coolant leaks into the engine block the car will act jerky since water is not compressible. Check the oil to see if it looks like coffee color (happens when water and oil mix).
No matter what be prepare to replace the lower/upper plenum gaskets, air intake and the tube that connects from the air intake to the EGR. New air intake comes without the tube. Replace to the lower plenum bolts. All parts available from

If it rains my 01 ford windstar will not want to run. It will back fire and miss. When dry for few days it will run better engine light is on but if you clear the codes it will run like nothing is wrong....

Windstars are known for lean codes caused by upper intake plenum gaskets. Also, there is a small tube going into the air intake hose that will pull out if you tried to install an air filter. It goes into the air intake hose between the air filter box and the throttle body on the firewall side of the hose. Check it. As far as the EGR concern you would need to provide the exact code. The lean codes won't cause what you're describing. The symptom you're describing sounds more like a misfire. Windstars are known for ignition coils going bad due to hairline cracks allowing moisture in and causing the misfire. The coil is located behind the intake plenum. Also, windstars are known for fouling #'s 1,2 and 3 plugs with oil. Good luck. Be sure to have your rear axle and front subframe checked for cracks at a ford dealer. There's a safety recall on them and if it's too bad, Ford will purchase the vehicle for 1.5 times the book value if it's unsafe.

2001 dodge 2500 4x4 high oil consumption

These are know for having a leaking gasket on the bottom of the intake that will cause oil consumption. To test for this take the pcv valve out of the passenger side valve cover and the crankcase filter out of the driver side. With the engine running put your thumbs over the holes in both valve covers. It should build pressure. If you feel it pulling a vacuum, the gasket is leaking. You have to remove the intake and flip it over on a bench to change the pan gasket on the bottom.

The knock sensor is threaded into the block of the engine, just below where the cylinder head sits. You will need to remove the intake plenum (upper and lower) to access this part.
