if you recall, last monday i posted syaing that my mechanic said that the reason my 530 was running so poorly was not the 02 sensors but a leaking intake manifold. He wanted 800 bucks to fix it... i decided to do the project myself.

during the process i carefully inspected and cleaned all of the pieces involved. all of the vacuum lines and gaskets seemed fine!! the pvc breater plate also seemed the be in working order. i was sure that when i got the car back together that it would still show symptoms. but it runs great!

moral of the story:
if you have a car problem, get it professionally diagnosed then fix it yourself. they're easy cars to work on and you'll save a fortune.
