Is it revving up and down, uncontrollably...? Also, check your ECU to see if it's not flashing any codes...

If it's not flashing any codes, then try re-setting the idle, following the proper steps of un-plugging the EACV. The ECU will throw a code, just re-set it, along with re-plugging the EACV connector.

Next, check your coolant level and see if you can bleed any trapped air out of the system. Just pull the cap off while the engine is cold. Then let it warm-up and the cooling fans kick on two or three times. It may take a while so give it plenty of time. The trapped air, will raise hell with the ECT sensor...

Post again if this does not help...
