I have an erratic 1000 to 2000rpm idle. does not matter the temp of engine. I can cruise down the road without using the gas pedal (40mph 5th gear). Have cleaned spark plug wells(replaced spark plugs Bosch quad tips), checked for vaccuum leaks, put injector cleaner in tank. Problem began AFTER replacing power steering pump. Also, the BVSV VALVE on the thermostat housing broke off(replaced). Also, replaced battery terminals. Cleaned idle air control valve. Also notice that if you dissconnect the IAC it does not effect the engine. If you dissconnect the TPS the rpms jump to a steady 3000rpms. Any advice will be appreciated.
Thanks,
ra
