Good morning.

So to clarify, you replace the TPS and throttle body and not the idle won't come down?

Do you have a scan tool to perform an idle relearn?

I have a snap on modis ultra
Expert:  Jared D replied 10 months ago.

That should do it. Did you attempt a throttle position relearn yet?

Jarred thanks for takieing my call I tried it manually running the motor for 3 minutes then off fo1 then repeated the process I never used the scanner what should I do
Expert:  Jared D replied 10 months ago.

Your scan tool should have an option under tests or functional tests. Each scan tool is different, but it should walk you through it.

Expert:  Jared D replied 10 months ago.

If the scan tool doesn't do it you can always try the manual way. Disconnect both battery cables and hold them together for about 1 minute. Then have a helper hold the throttle plate closed by hand while you re-connect the battery cables. The throttle plate might try to open a little while holding it close, that's ok. Once the battery has been hooked up you can let it go. Then start the engine and see how it idles.

Jared does the key have to be on
Expert:  Jared D replied 10 months ago.

When you disconnect the battery? No. The key should be off.
