First, I have to admit I'm a complete newbie, so please bear...


Used seafoam on throttle body, and slowly sprayed 1/2-1/3 bottle into intake manifold through clamped tube. I got a whole lot of black smoke, and later, these codes:

P0123 - Circuit High Input
P0507 - Idle Speed RMP Higher than Expected (it feels like it's come down now tho)
P00223 - Circuit High Input


Any tips for this newbie? Took it to the Zone for these codes. We disconnected the battery and restarted the bar, but the check engine light remained.


Thanks!

 

Disconnect the battery and pump the brakes a few times.

You will probably need to do an idle volume relearn procedure.

I've never seen anybody use that on the throttle body...its possibly you caused some damage to it.

 

Thanks. Where can I find info on the "idle volume relearn procedure?"

 

do a little "search"
