Need some help with DTC's
Hey fella's, I'll just cut right to it. I purchased a 1995 GMC 1/2 ton pickup.
Here is where I'm at. I did a complete tuneup plugs, wires, cap, rotor, timed and changed oil. It runs o.k. it stumbles when it idles in Neutral and in gear.
I checked for vacuum leaks and didn't find any.
I ran my very first data log and it threw 30 codes! Here is the list of the codes & a site that explains them. This is my first data log on anything. Here are the list of codes and a link to their definitions. One of my questions is, with all of these codes being thrown could I have a problem with my ECM?
Codes: 13,14,15,16,21,22,23,24,25,28,31,32,33,34,35,36,37,38,39,41,42,43,44,
45,46,51,52,53,54,55.
