Codes
I have a 93 five speed with 78000 miles. Check engine light came on . Hooked up the OBD reader and got two codes. Replace my tps and air sensor. Hooked up the reader and got a different code. Replaced my cam sensor. Got a different code again! I found an SC in San Jose (I live in Merced CA.) and pulled the ECM module and the module that controls the suspension / steering. I replaced the ECM and no more CHECK ENGINE LIGHT. Besides the CHECK ENGINE LIGHT , the cars steering was acting up, the ride control light would flash on and off and the idle would act up. After I replaced the module that was located under the package tray (suspension module) those issues went away also. The car had sat in my ex's garage for quit a few years and maybe this caused both modules to fail. It gets hella hot here in the valley .
