Buick high idle speed at start

[HEMI-V8]

Okay.

 

And should I clean the Injectors equal ?

 

With this method:

that's one way of doing it, i'm not a fan of running solvents through in the normal direction, but running it in reverse can certainly cause some interesting stuff to come out of the injector.

 

some of these old injectors can fail electrically as well, usually showing up as significantly less resistance than there should be. going off of memory, these should be near 12 ohms.

UPDATE:

 

Finally I found time for my Buick and I have done these things:

 

- NEW Denso iridium spark plugs

- NEW IAC

- NEW EGR gaskets

- NEW upper manifold (plenum) gaskets

- NEW throttle body gaskets

 

 

After running the Buick I think it´s not really better.
