Hi all,
Long time reader. So thank you all for the help over the years, but I could not find anything on this sensor in the picture. Long story short, I developed a knock/tick in the upper engine and figured out it was coming from this unit in the picture that plugs into the intake manifold just after the throttle body. The knock/tick only happens at idle after the car has warmed up. If I unplug the electrical connection and the vacuum line, the knock/tick goes away. I assume I need to replace the unit, but I can't even figure out what it's named or its part number.
So,
#1, Do you think replacing the unit should solve the problem?
#2, What's it called or where can I buy a replacement.
#3, Can it just be cleaned?
#4, I'm sure I'll find out after looking up the part, but is there a related gasket etc I should buy with the part?
