1994 Ford Ranger STX 2.3L Hesitation, Surge, MIL Lamp on
Posted to Ford Driveability on 10/8/2001 10 Replies

If I clear all the codes, and restart engine, the engine races up to about 2000 rpm, the as it comes back down to idle, the mil light comes on and all the codes are set. The 998 hard fault code is a new one on me.
