1983 LTD crown vic idle too high
 

hi

bought today this 83 crown victoria and the idling appears to be high.

is there any adjustment to it? such as an idle control valve? I do not hear any vacuum leaks.

is there any DIY troubleshooting guide?

I have experience with fuel injection but not with this model

Thanks!

I also have some problems with the fuel level. What is the spec (ohms at Low / Full) for the fuel level sending unit and where can I find it?

Does it have the 5.0L w/CFI or 5.8L w/CARB engine?

here is a picture.

which one would this engine be?

Hope you guys don't mind , but I think I see a throttle control piece and It does appear to be with a carburetor. I could be wrong !

A picture without the air cleaner on the intake would be more useful to easily identify what you have.

Hanky is right, the throttle control piece appears to be for a carb so the idle should be adjustable.

Here's a picture of a CFI unit...

My engine is 5.0 fuel injected. And the cause for the too high idle was the throttle wasn't closing properly. Either dirty or the spring got too weak. Push it back with the hand and it idles correctly. So not a big problem!
