Default 93 No MAF??????

I had a 86 corvette before my 93 and I noticed my 93 doesnt have a MAF.
But it does have a thing in air duct which im guessing is a MAT sensor.

Can this be cleaned with electrical cleaner safely???
It looks kinda dirty and wondering if it could be causing some of my warm"when car is warm up" start up issues.

Car starts fine when cold.


TIA Repzard

if the inside is that dirty, I would be sure the air cleaner is sealed right.

can the MAT be cleaned? I donno... I would consider compressed air.

It should be able to be cleaned safely with CFC electrical cleaner.

It's just a thermister and can be cleaned, but it isn't like a maf that gets dirty and reports false airflow. You probably won't notice any difference and it's likely still reporting fairly accurate air temp. Additionally, variation in reported air temp isn't going to effect too much even in a speed density system.
