Dielectric grease... yes I searched :)

Today during the rain I encountered a puddle and slowed down to not swamp my engine with water, the puddle was on the passenger side and didn't want to suck water up in the air filter.

But I believe some of the connectors inside the engine bay got wet, as the LC would idle low and I would have to put the car into neutral and keep the RPMs up. I know that the alternator has some issues, dash lights blink when signals are on. That issue is being addressed.

My question now is if I install dielectric grease on the connectors around the intake, idle control valve, etc would it prevent water from getting in there and causing the rough idle? Before this, the last time I had a similar issue was after I washed the engine bay. After watching the video below, I understand that dielectric grease is better suited for high voltage connections like ignition system.

Is the air flow sensor, and other connections around the intake and going to experience issues or would it be beneficial to use grease in them to protect them from water, and other corrosion.

I usually use dielectric grease on electrical connectors if I take them apart. My truck still sputters some times at the car wash. I thinks it's water getting in the distributor. If I leave it running, that seems to help.

I’ve been told to fill 2 of the 3 holes in the distributor to keep water out. I have yet to do that, that very well could be my issue today too, but wanna start taking preventive measures.

Good to know I’ll try that.
