High Idle After Restart

[87ComancheLB]

Were the injectors upgraded from single port to 4 ports? Like I said I believe but not sure if there was a vacuum leak on mine all I know is it no longer restarting at high idle, maybe the older single injectors had sticking problems was the reason I changed them on mine and all is good now.

Yes I replaced the injectors with the Volvo injectors. The high idle was there before and after.

Of  course it was. The injectors have nothing to do with idle flare on start-up. It's TPS and it's related grounds/connections.

That's what I thought as well.

I'm still intrigued by the power latch relay. Might that have something to do with it? Some faulty interpretation by the computer?

IDK. Intermittent idle flare has always been TPS related.

I didn't read the list. Was clean the throttlebody (especially the IAC) on there?

First post has an index in it. Post 11 is TB and IAC cleaning.
