sensors that get dirty/gummed up? - 90 CV

[1990LTD]

I want to go through my car stem to stern and clean up electrical connections and sensors that have probably never been touched before.


Where do I start? What are sensors that most commonly get dirty or crusty or whatever? The plan is to clean up prettymuch every connection and harness I can find but I'd put good money on me not finding more than a 3rd of them.


What to clean them with? I use electrical contact cleaner for, well, all electrical contacts....is there anything better or more suited for automotive use?

What's good preventative maintenance to ensure my electrics last as long as possible? I don't want to end up cleaning up something only to remove a protective layer of grease or something and fry it

the intake air temp sensor can get all fouled

Where in/around the intake is that?

[marquisman]

on the driverside, bellow the plenum, by number 4 injector

below the plenum? you figure it would be easier to do with the upper intake off? may save that one for intake day.

real easy to remove, just need a deepwell socket. Before you put it back in, clean the threads out and apply some non-hardening sealer to the threads. A smidge of Permatex #2 will do fine.

He meant to say #5. As Gadget said, really easy swap. My new one had sealer on the threads already. No issues out of it.

All ford v8s are numbered the same, right? If you're facing the distributor 1-4 are left and 5-8 on your right?
