Re: [ihc] Weird engine problem - calling the experts

["James Lidberg" <jameslidberg@xxxxxxxxx>]

No expert here, but ... Sounds like a vacuum leak. Has that been measured?

I did my intake manifold a couple years ago. There are several expansion plugs on the underside. They can leak.

The manifold can be cracked.

If the intake is EGR, it is possible to have a vacuum leak from the EGR valve into the manifold, or way too much EGR 
also.

It is important to have the the EGR passage ways clear. I could not chip out the carbon from the manifold, it was so 
hard I had to have it hot tanked to get it out.
