96 ranger high reving problem

Im having a problem with my 1996 ranger its a 2 wd, 5 spd, 2.3L motor. When i start the truck the rpm's go up to 4000 , then drop to 3000 , and finaly drop to 2000 at some point it will drop to 1100. Then if i start driving the truck and stop the revs go back up to about 2500 rpm, and only sometimes would drop to 1100 and if i give a bit gas it would go back to 2500 rpm again..

I replaced the Throttle posittion sensor (TPS) and the sensor beside it but same thing.. No improvments .. The spark plugs are good on it the air filter is clean .. The truck has 228 xxx km..
Any help would be great thanks in advance

Re: 96 ranger high reving problem

I had the same exact problem on a 93 Saturn SL-2. I suggest changing your PCV valve. You can purchase one from a local auto parts store, and for a Fram it should cost you about 2 dollars. Motorcraft is a little more expensive, but they are practically the same thing. Installation is very easy, and requires only removing a small flex hose and pulling out the old valve, then reverse for installation. A clogged PCV will cause high idle problems, and it is the cheapest and easiest thing to change, so that is a good place to start. Please respond to this thread if the PCV valve fixes the problem as a reference for others.
