First off i serched but after a day worth of looking i have nothing.

Anyway heres whats going on. When i start the car all is well untill it is fully warmed up. Once it is all the way warm it will either A) idle at 1500 like its cold again or B) jump form 13k-17k. So i adjusted the tps and set it back to what it schould be and it still did it.

So i disconnected the BAC and the TPS and it will hold an idle better but it still jumps arround from 750-1000 then it will go back to 13k-17k. It will also kill its self if it idles and i floor it then let off after a sec or 2.

so tell me whats wrong with my car! this bouncy idle is bothering me

 

allright got a lil update. i drove it today w/ the tps dissabled but the bac connected. same symptoms

 

After you set the TPS and checked the BAC, did you go through the process of idle speed adjustment? Set the idle speed to 750, engine fully warmed up and your pulsing idle problem should go away.
