Problems with codes

[emoshn]

Car has been idling poorly, especially on initial fireup...thought it was the IAC being dirty or blocked, so I got the kit to rebuild the TB, but before I got started on that, decideed to run some tests to see if any codes were showing. I have the cheapie little Killebrew thing which basically just replaces the paperclip. Has several different plugins for various systems. Knew I had problems with the FX3 system and pulled those codes. Then I put in the ECM plug: Codes: 16, 26. & 32. Then I plug in the CCM plug in: codes (and it shows a small number) 1. H74 4. H16, H26, H32 (which interestingly are the same as the ECM codes) 9 --- 1.0 --- and finally the SIR plug flashed 12/13/12/13. This stuff just plain scares me. I know 32 is EGR associated ( just replaced the EGR and EGR solenoid last year). what are the others? Any help will really be appreciated. a real novice here. I have an AC/DC volt and ohm tool and that's about it. Thanks...and please be gentle. :banghead:

Have an 87 and check gm codes: can't find 16 or 26, but 32 is the EGR
good luck... sure someone else will chime in.

Under "In Depth Info" Check "ECM COdes". Under "Fact Sheets" look at "Trouble Code Recovery". It will be a place to start. Also, the "H" in front of the code is a history code.

Good luck.
