Cleaner and DiElectric Grease

[Khronik]

Due to a possible tps or maf issue im going to do some cleaning and checking of connectors

Im guessing I want the battery disconnected while doing this but my question..
Is it ok to start unplugging everything and using deoxit/progold sprays+dielectric grease on all connectors?
or is there no need to use dielectric grease after using deoxit and progold?

I read somewhere that some of the connections are very thin and dielectric grease can actually cause problems
dont remember where I had seen it and cant find it again

Safety 1st! Disconnect the battery.
Clean the connection(s), grease and reconnect.

I've had success using CRC QD Electronic Cleaner on corroded and gummed up connections followed by CRC dielectric grease. Essentially every connection under the hood should have some dielectric grease protection due to the weather conditions the engine bay is always under. Unfortunately I have no experience with deoxit or progold. Be sure they are automotive electrical connection safe.

I used a bunch of stuff, Radio Shack contact cleaner, emery cloth, wire brush, small screw drivers, brake clean, etc. Basically, get all of the green off of every connector. Then apply di-electric grease on each contact of each connector. It helps seal out the moisture. It won't interfere as long as the connector makes good contact. If the connector connects loosely, tighten it up. You are just avoiding a problem down the line.

Be careful getting the connectors off the injectors, IACV, MAF, PTU, CAS and all of the ones that have the metal clips. They are usually very brittle and break easily. Also, don't be surprised if all of your coil pack connectors break when you try to remove them. If they go back on snug, you will be fine.

^ Correct.

No to dielectric grease on connectors associated with the O2 sensors.
