I have a 94 4cyl 5spd. I just did a complete rebuild on the motor and have replaced the dist., tps, map sensor, o2 sensor, pcm, idle solenoid. I scrubbed the throttle body and have done every other r & r I could think of. The problem I'm having is that the motor will not rev over 4000 rpm. It makes no difference whether it is in neutral or any other gear, as soon as it hits 4000, it starts to cut out. Does this vehicle have an accessable rev limiter or is this something that can be programmed into the PCM? I'm at wits end here and could sure use some help. Thanks in advance!!
