The valve's metal disk houses a vacuum diaphragm, spring, and plunger. Also, do you know if he cleared any trouble codes from the computer memory after replacing the valve? There may also be other symptoms.
I think it's injector flow report back on what you find. But pull down the codes again and see if cylinder 7 still appears or there are other issues. Inspect the harness for opens, shorts ,broken or cracked wires. The first time the diagnostic fails, the control module stores this information in the Failure Records. Check the other ones first, if there are more. A trouble code has been stored and a malfunction indicator lamp has been illuminated. The car loses power at certain points, usually when I get to a high rev.
Sometimes the path which is made out of graphite can ware out or dirt and grease can contaminate it. Look up the other , please use the search box.
