WTB Scorpio Exhaust near Dothan,AL

I need the complete exhaust after the y-pipe(cat or test pipe,muffler,tailpipe). I have a welder so exhaust could be chopped for shipping if the price is right. Alternatively I would be interested in the flange and a section of pipe that hooks to the y pipe before the cat so I can build my own exhau...

Re: Scorpio High Idle🙄

The attached Technical Service Bulletin (TSB) was probably already performed on your Scorpio back when it was young. But the TSB does outline how the idle screw is adjusted. Hope it helps. Steps 8-25. tsbidle1.jpg tsbidle2.jpg Thanks for the info. I don’t have an emissions sticker or the TSB sticke...

Re: Scorpio High Idle🙄

I haven’t opened them, not really sure what I’d be looking for . I’m assuming the catch code is the ECU code like LA3 /PE etc? Once you open up the case just look for the two or three blue/green colored capacitors. Google "Ford Capacitor Leak". You'll be reading all day. The Scorpio catch...

Re: Scorpio High Idle🙄

Late to the dance on this one - glad to hear you solved it. That said, have you pulled the EEC-IV PCM to check the integrity of the capacitors? We should all be doing that. While you've got it out, tell us the catch code. Since switching to the later PCM I have not had a high idle condition. I have...

Re: Scorpio High Idle🙄-SOLVED!!

SOLVED!

It ended up being that the vref and sigrtn wires were reversed.

It either happened when I replaced the connector or it explains why it was sitting in a field

Now on to dealing with 5-10 yr old gas and making it idle.

Re: Scorpio High Idle🙄

Does this pin out look accurate?

Re: Scorpio High Idle🙄

Someone please correct me if I’m wrong, but, TPS voltage is measured by putting (+) lead on pin 47(TPS SIG) and (-) lead on pin 46 (SIG RTN)?

Re: Scorpio High Idle🙄

I noted earlier I "think" the throttle plate/butterfly should close fully with no pressure from the accelerator cable. That's what I've observed when I removed the TB for cleanings. So, I'd remove the TB, thoroughly clean it including passages, adjust the stop screw if/as appropriate. YMM...

Re: Scorpio High Idle🙄

Ok so I spent $80 on a factory service manual but the idle speed stop screw adjustment is not in this book🙄

In the troubleshooting tree for code 23 it says to ensure it’s correct before proceeding.

I have in fact messed with the screw so what should I do? Where can I find the procedure?

Re: Scorpio High Idle🙄

As always each time you fix something, disconnect battery and wait a bit and reconnect and re-capture codes to see if you actually addressed the issue. I think your TPS is bad. Unless you have proven that this particular error code is gone. One almost never messes with the idle screw on a Scorpio. ...

Re: Scorpio High Idle🙄

Edit above: The throttle body should be thoroughly cleaned (bore/butterfly and passages). I think the butterfly should close completely at idle (re idle screw) . YMMV The reason I ask about the idle setting is the code says out of range. I’m wondering if I’ve closed it too far and if the ECU doesn’...

Re: Scorpio High Idle🙄

I'd install a new ECT; its role in engine manage is key. (And MAP sensor and ACT sensor just as part of a tune-up on an unknown engine maintenance history). The EGR valve could be carbonated up (equivalent to a vacuum leak). The trans shift modulator (passenger side of trans) operates via vacuum so...

Re: Scorpio High Idle🙄

What’s the normal TPS voltage range the ECU is looking for?

I’ve messed with the idle stop screw so it may be causing an issue?

Re: Scorpio High Idle🙄

So far all I can think to do next is:
-Revisit vacuum leak search.
- Try to reset base idle with iac unplugged(need to find procedure for that)

Re: Scorpio High Idle🙄

The car had been sitting but I’ve had no luck finding any vacuum leaks, to include capping off the manifold port.

I’ve never seen it run good as it’s something I saved from a field/back yard.
