1990 Mazda Protege Service and Repair Manual
Fitment on this one is narrow by design: the 1990 Mazda Protege factory service and repair manual is tied to this exact year, engine and trim, so the clearances, torque values and adjustment sequences it prints are what Mazda published for this car and not a figure carried over from an adjacent model year.

Known issues on the 1990 Protege. One recall is on federal record for this model year, and it covers the ignition switch: grease applied to the contact points inside the ignition switch may become conductive and overheat, and if the ignition switch overheats there would be an increased risk of a fire. Mazda's campaign was a broad one, covering the Protege for model years 1990 through 1998 alongside the MPV, 323, MX-3, 929, MX-6 and 626. Owners have submitted 41 complaints for the year. The factory diagnostic and repair procedures behind that system are here.
An ignition switch inspection and a routine service on the 1.8L four come back to the same thing: the OEM procedure and the correct specification for your 1990 Protege.
