from my recent research (it's 4am now), i've figured out that the CODE 4 i'm getting is the crank angle sensor? i was on my way home and i got a cel. i was on the freeway when it happened.

during cruising speed, my car would suddenly studder for about a second every 3 seconds or so (here and that, not totally continuous). i could see that the rpms would drop...sorta sporadic looking on the tach.

i just got home thankfully, and checked the cel. its defenitly a code 4. what do i need to check? what do i need to do? should i just replace the CAS or should i try something else?

***FYI*** i unplugged the harness' from my ecu when i was doing my air/fuel gauge about 3 weeks ago. also, my rex has 200,XXXk on the motor, and i'm unsure when the CAS was replaced last.

any help would be great, especially since i have tomarrow off, i could work on the car. thanks guys...

Check the pins and wiring @ the ECU and try resetting the dizzy, unplug both clips on the dizzy unplug the battery and see if it still throws code 4.... I had the same issue with my B20 throwing code 4 and it turned out to be the wiring.... I believe the Pin is B10 or B12, its orange I think, can't quite remember... Good luck... O if you have another dizzy layin around try it, your CAS might be dead...
