Rusty EGR soleniod?
I replaced my EGR soleniod tonight, and decided to rip open the old one to see if I could tell what was wrong. Well, the metal circle in the center of the rubber vaccuum dealy (inside the transducer portion of the valve control) was badly rusted and caused a hole to form in the rubber, which was getting kind of dry rotted in the center anyhow. There was moisture in there too.
EGR valve itself was a pain to replace (tight area), but appeared to be fine.
After starting the car, my idle used to jump way up to 2000 rpm, then ease down to 800. Now (when warm starting) it goes to 1000 and back to 750. Will I notice any other performance differences?
Also, the PCV hose is so trashed I don't know if it's passing exhaust gas, or flattening out when I accelerate. I gotta say, a lot of the rubber parts on these cars suck (last week I replaced cradle bushings, rack bushings, tie rod bushings). I guess I should shut up and be happy they lasted 9 and 1/2 years / 124K though!
I'm a brake caliper (stripped threads), valve cover gaskets, CV boot (small leak) and a set of tires from calling this little project done!
Should I fear the valve cover gasket replacements? All the crap I hear about brittle harnesses, fuel rails, etc scares me...
