Hi need help with this its a bit frustrating. I installed a new throttle body with gasket and now it is idling at 1k and 1,2k with a/c on. It was doing the same thing prior to the install I figured it should fix the problem. but it hasn't. i have done the relearn and ecu reset. With the relearn it would drop the the rpm to 750, when when i start the car it would go back to 1k. the SES lights goes back on. i have had the code read and each time its p0507. anyone have a clue on whats going on? i killed the battery in hopes it reboots everything.

 

Check all vacuum hoses, intake manifold/upper plenum for leaks.

 

Is everything stock/OEM or do you have mods?

 

the car is stock.

Disconnect battery overnight. Reconnect next day, do first two relearns steps from here...

Drive car around to get engine hot then repeat all three relearn steps. I was having the same problem about two months ago then ran across several threads from people who couldn't get their idle to stabilize or drop to 750 - their solution was the hard reset of the ECU.

 

same what dave said, i did all relearns and didnt do much until i disconnected batt overnight, and next morning, it was fixed after warm-up. one of the steps should clear the c.e.l. tho.... u had the prob before tho?? then u replaced the t.b.?? if u didnt disconnect batt before install also..GL

 

thanks for the feedback. i disc the battery for two hours and the idle went back to normal.
