High Idle!?!?

so my truck is idling at about 1200 rpms, constant. when i put it in drive or reverse it drops to about 750. the truck usually idles at 750. the only thing i can think that may have caused it is i just changed the ground cable from the terminal to the frame to a 4awg wire. (installing amps) when i finished and reconnected everything it idles high.? anyone know what may have caused this? maybe a computer reset or something? i had the batt disconnected for about two hours.

 

My trucks the same way.

 

has it always been that way? mine just started doing it the first start after changing the ground wire

 

i think your a liar........lol, j/k.... dont worry, mines that way too... i thought somthing was wrong too... lol... but then i thought about it.... your good

 

the only reason i have concern is because it just changed, i just want to make sure i didnt fry something in the process of changing the wire, or some how mess something up in the computer.

 

i wouldnt worry about it. all tacomas idle high and quick til they get the engine operating temps up to par. helps warm the engine up a lil quicker.

 

^^^ beat me to it.... its normal

 

Yeah exactly what Tacomaman was saying, my truck does it and its Perfectly normal, when you drop it into gear the computer figures out that you are about to go somewhere so it drops its idle revs
