Engine Rpm Gone Up



Hi Guys,

Yesterday when I switched on my car ignition, no lights were ON on the dashboard and I couldn't start the car. I twisted the battery positive terminal connection (suspecting this was due to the battery problem). Then the dashboard lights were ON and the car did start. But, the engine RPM was a bit higher than normal (I don't have an RPM meter to specify the value). At the operating temperature, RPM was lesser than the cold one but, it was higher than the normal RPM at operating temperature. Can anyone tell what could be the problem?

FYI: Mine is a toyota corolla AE100 (YOM 95).

its possible that your ECU had gotten reset as a result of é battery being disconected for a prolonged period of time

when this happens i've noticed é engine revs a tad high until é ECU recaliberates itself - should sort itself out after a days running...
