Default Re: Cleaning the EGR valve and other questions...

As for P0507, are you also getting an abnormally high idle (2,000 RPM or so)? If so, spray some brake cleaner around the cyl #1 area on the intake manifold. If the idle changes, chances are is that the intake manifold gasket is bad. From '99-2002, the intake manifolds were misinstalled at the factory, causing this little wrinkle around the cyl #1 area right around... NOW, if not sometime before then.

As for a timing belt being replaced... uh, no you (or someone else) didn't. All S-series from 1991-2002 use a timing CHAIN. You might be refering to the SERPENTINE belt instead.
