ENGINE IDLE THIS HIGH?

I have a ford e250 5.4 liter. It idles at 2000 rpms in park and neutral and idles at 1000 rpms in gear. I replaced the idle air control valve and it made it worse.

Any ideas on what could cause the vehicle to idle this high. Why does the van run the same wether the maf is installed or removed.

Do you
have the same problem?

That could indicate a faulty MAF, which can cause erratic idling.

Have you checked for vacuum leaks?
