Re: 02' V6 RPM's staying high while shifting

If it's staying high between shifts -it's a combination of 2 things NOT related to idle. Emissions and the flywheel. THe 6 has a GT flywheel which is really too heavy for the engine & compression, this causes the flywheel to retain the RPMs between shifts. Also the engines are programmed to do so because the emissions are cleaner that way. A chip or programmer can take care of the engine run-on (but you may not pass emissions - for the 1st part, you'd have to swap to a lighter flywheel.
Now this is different from high idle, if it's idling high, that's a separate issue usually MAF, Idle Air Control, or a Temperature Sensor. If someone put in a 160 degree thermostat, that can cause it, as the engine never knows to turn off the elec`tronic choke.
