I might have revived a cursed thread earlier. Apologies?
Any ideas what my issue is?
I removed throttle body and saw an impressive amount of hardened carbon. Cleaned that all off.
Here's the mystery to me, I removed VSV and tested with ohm meter and applied vacuum and voltage. My factory vsv is behaving just like the new replacement. Both reading about 33 ohms. However, when applying vacuum with no voltage neither hold at all, air passes right through. If I plug the open port, of course it'll hold. My impression is that they should hold vacuum until voltage is applied. Both exhibit a clear audible click with voltage.
Any help would be appreciated. I'm unsure whether to replace the vsv and throw everything back together or use my original because maybe it was the carbon build-up. What are the odds my replacement VSV is malfunctioning the same way my current one is?
