ok my vehicle has about 42000km on it and I took off the throttle body. cleaned it with throttle body cleaner. although have a question with this much km on it should the back of the throttle plate be brown color. like oil? seems also on the opposite side of the plastic header not sure name the seams seam oily. like if its leaking. thinking now if I should replace the pcv valve?


also little accident removing the connector on the little sensor on the tubing and broke the clip red piece u pull back and the black tab. now it kinda floats up and down without staying in place. can I get a new one from dealer?

 

I watched lots of youtube cleanings but, I saw no benefits.
