I'm posting this in the noob section just in case, this looks like a 4, 22, 24, but for doesn't show up in any of the writeups I've found. The best (89 3vze) had beenrunning rough with symptoms similar to a bad iat sensor or a clogged idle air control valve. It starts rough and runs rough at low rpm. It could also be bad/sticky injectors. Any tips/ideas? I uploaded a video of the light flashes just in case.

Thanks in advance,

That first code is a code 14 not 4 and the others are correct as you noted.


Code 11 Momentary interruption in power supply to ECU (electronic control unit or computer) up to 1991
Code 12 Engine revolution signal missing
Code 13 Rpm signal to ecu missing above 1000 rpm
Code 14 Igniter signal to ecu missing
Code 16 A/T control signal missing from ecu
Code 21 Main oxygen sensor signal fault
Code 22 Water temperature sensor circuit fault
Code 23 and 24 Intake air temperature signal fault
Code 25 Air/fuel ratio LEAN
Code 26 Air/fuel ratio RICH
Code 27 Sub-oxygen sensor signal or heater circuit fault
Code 28 No.2 oxygen sensor/heater signal fault
Code 31 and 32 Air flow meter circuit or Vacuum sensor signal fault
Code 34 and 36 Turbo-charging pressure signal fault
Code 35 Altitude compensation sensor signal fault
Code 41 Throttle position circuit fault
Code 42 Vehicle speed sensor circuit
Code 43 No starter signal to the ecu
Code 51 AC signal on; DL contact off (in trany shifter with diagnostic connector jumped)
Code 52, 53 and 55 Knock sensor fault
Code 71 EGR system malfunction
Code 72 Fuel cut solenoid signal fault
Code 78 Fuel pump control signal fault
Code 81, 83, 84 and 85 TCM communication fault

 

Ah, check, I thought that that '1' blip was (I read the documentation as saying) a blip that you get before the whole list of errors repeats. Sad day, sounds like everything is wrong :p

 

Download or if you have Factory Service Manual do diagnostic procedures.
Start simple, check for vacuum leaks and loose or corroded wiring.
It's not that bad, get out the multimeter also.

 

Also, funny story. I went to crank the beast last night to see if I was getting any spark off of the main coil (like it says to do here https://www.yotatech.com/forums/f116...-start-146237/ ) and it made the sort of starter noise that you usually get from a corroded battery contact. Further investigation led me to finding that the bolts on the starter had backed off a bit, and that the poor contact is actually from the starter body to ground :p More to come, I'm sure....
