aight, so lately my idle has been actin kinda wierd by sometimes bouncing between 100-200 rpms (not 1000 to 2000, thats just how much it actually bounces) and i was wondering what it was. so i went under the hood, and noticed battery acid all over the + and - battery thingys lol.. so we used baking soda to nueturalize it and now its all off. We did all this yesterday, and before i could drive it my dad took it away for 24hrs for skipping school to go drive lol. but i was wondering if this battery problem could be part of my idle problem?

 

No. Dirty battery terminals wont affect idle.

 

especially when the car runs off the alternator when its running

 

found out what it was, i put in my vtec controller a few weeks ago, and it was running fine, but the idle problem started taht day. then we got to thinking about it anyway, and the vtec controller sets back a chipped ecu to stock settings, so it was pointless to have the vtec controller anyway. so i took it out and it all runs fine now lol. we think the controller is possessed
