How to pull codes from ecu with check engine light
Since they limit here to only 5,000 characters per post, I can't edit my post above, how I want.
So here are the Error Codes for; 90' Lx 3.0L V6 11O,R,CSystem Pass 12RCannot control rpm during Self-Test high rpm check 13RCannot control rpm during Self-Test low rpm check 14CPIP circuit failure 15OROM test failure 15CKeep Alive Memory (KAM) test failure 18RSPOUT circuit open 18CIDM circuit failure19OFailure in ECA internal voltage 21O,RECT sensor input is out of Self-Test range 22O,R,CMAP sensor input is out of Self-Test range 23O,RTP sensor input is out of Self-Test range 24O,RACT sensor input is out of Self-Test range 25RKS sensor signal is not sensed during Dynamic Response Test

Tried gettin codes but all my check engine light does is stay on the whole time, but as soon as i turn on my car it turns off. I grounded the wire to the single red wire w/ white stripe. im lost and my car only starts once in awhile. is my comp fried?

Thats normal procedure. In the ON position, the cars check engine light will stay on. Make sure u are grounding the correct wire. Small little spade female connector with white and red stripe. If you have no codes, then your good!

I tryed the test and when I ground the red/white wire. The light just stays on but my check engine light stays on while I am driving so I know there has to be codes. What do I do I have a 89 gt.

Where are u trying to ground the wire to? Make sure u have it grounded to a good spot, say like a bolt on the driver side strut tower or even a wire long enough to put on the negative portion of the battery. If that dont work, replace the wire u are using, if that dont work, something is up with the wiring..

Ok guys, my friends 1989 Probe is running like ****. It takes forever to start and when it is running, you have to open the throttle slowly. If you open it fast it bogs and dies. You have to open the throttle VERY slowly to rev it up, any faster and she bogs clear down and dies. So we ran the code tests and here is what we got.
Turned the key on.
Check engine light came on for about a second then shut off.
Blinked 8 times, paused, blinked 1 time, paused, blinked 1 time, paused, blinked 2 times, paused, blinked 1 time paused, blinked 4 times and paused.
We checked it over and over and got the same thing.
8 - 1 - 1 - 2 - 1 - 4
This appears to be code 81, code 12, and code 14.
Now, something has to be wrong as there is no Code 81. But the other two codes sound legit. I am pretty confident that since we got a code 12, the TPS is probably faulty. When we unhooked the TPS, the car acted the exact same way as it did with it hooked up, also leading me to believe the TPS is bad. Any ideas?

Try this for size...this is my interpretation...
Code 8, 1, 12, 14. These are definately your codes. I have the pauses and stuff beaten into my head since I check on my Probe all the time..Heres what they are telling you...
01 - Profile pickup - If I remember right this code has something to do with ignition diagnostics, check to make sure u are getting good spark.
08 Vane Airflow Signal - Check to make sure the plug on the metal thing right by the intake tube (black tubing) is plugged in tight, these plugs seem to wear over time and tend to get lose. Also your VAF may be bad, If so hit the boneyard and get one. I got mine for 10 bucks (about 150 new in store)
12 Throttle Position Sensor - This could be bad or out of adjustment. If its never been messed with, probably bad. If still good, to a search on how to adjust this. Its the little black round thing with 2 circular screws on the back of the throttle body, cant miss.
14 Barometric Pressure Sensor - Ive never messed with this thing, do a search, see what you get.
Any other questions, Haynes manual, at your nearest Autozone, Chucks, Napa, Checker, Pep Boys, 15 bucks, Best 15 bucks you will ever spend.
