Now, I understand this, but how in the heck do you check the codes? I don't have access to a friends computer crap anymore. I know exactly where to connect the paperclip thing, but am really confused on how exactly to do it. I did do a search on this forum and found nothing. Also tried searching on the net and found not much of anything. How exactly do you know what code it's throwing out? I understand the lights flashing crap, but I’m scratching my head right now trying to figure it out. Hopefully some of you will know.

Now with my CEL, seems kinda weird. When running the car on the road (well when it was on the road) , if I just lightly use the gas pedal, no CEL would show. On the other hand when I was going up a steep hill and had to get on it to keep going (also moved out out of overdrive, but not likely any relevance, or could be a positioning sensor...) it showed up as soon as I got on the throttle good. Seems kinda odd.

Once you get the code/s I can tell you what they mean...

Im not exactly sure WTF all that means. How do you know what code it is by just flashes and pauses? Sorry, I'm a pretty dumb person. I have to see it on my own to figure it out. Guess I'll see this weekend what it all means...

Just read it over slowly and visualize/think about it.

One flash = 1
Two flashes = 2
Three flashes = 3
..etc..
A short pause inbetween means next digit and a long pause means a new code being displayed.

The code will always be two digits...no shorter and no longer.

Thanks Brando...I get it now. You should feel like you've accomplished something. It's hard to get me to understand something.

Now watch, I won't get any codes out on my ECU

A lot of times the Oxygen censor with throw a code when you’re under pressure. It should be about $20 at the parts store, and be careful removing/installing it without damaging the wire. Here are your codes:

Diagnostic Trouble Codes - 1987
Oldsmobile
13 Open Oxygen Sensor Circuit
14 Coolant Temperature Sensor (High Temp Indicated)
15 Coolant Temperature Sensor (Low Temp Indicated)
21 Throttle Position Sensor (Signal Voltage High)
22 Throttle Position Sensor (Signal Voltage Low)
23 Manifold Air Temperature (MAT) Low Temp Indicated
24 Vehicle Speed Sensor (VSS) Circuit
25 Manifold Air Temperature (MAT) High Temp Indicated
32 Exhaust Gas Recirculation (EGR) Circuit
33 Mass Air Flow Sensor (MAF) (GM/SEC High)
34 Mass Air Flow Sensor (MAF) (GM/SEC Low)
41 Cam Sensor Circuit
42 C3-I EST or Bypass Circuit Failure
43 Electronic Spark Control (ESC) Circuit
44 Oxygen Sensor Circuit (Lean Exhaust Indicated)
45 Oxygen Sensor Circuit (Rich Exhaust Indicated)
51 PROM Error
52 CALPAK Error
55 ECM Error

Thanks. I'll have to check the codes tomorrow if there is cause the computer has been re-set too many times. Didn't know the cooling fan would come on, though when you do the paper clip thing. I got lucky on that one cause dad was workin under the hood

Ah...yea...the cooling fan comes on.

Oh now you tell me, punk! After my dad coulda lost a hand

Must be some diagnosis thing I guess.

Edit: BTW this beast is comin home tomorrow, w00t!

Code 32, something with the EGR? Can somebody spread some light on this issue?
