I pulled the MAF plug off mine (1993) to clean it cause im trying all kinds of things to get it to run right…i notice there are 4 “holes” in it but only 3 metal connectors on it. When you look inside it there is no metal contact in the hole on the far right, but there is a pin on the MAF for it…can someone look at their plug to see if there is 3 or 4 connectors in it (the part where the wire goes into) cause if im missing a contact in there it could be the problem.
The plug only has 3 prongs. It’s how it is.
