Hey guys, back again with a couple questions, first of all on the way home tonight I was waiting at a light and once the light turned green I hit the gas and the engine seemed like it was miss-firing/stuttering until I took my foot off the gas pedal, now it had done this before after a few weeks of having the car, but it never brought up any codes. Tonight was a bit different, it seemed like whenever I pushed the pedal in more then about 20% it would do the stutter until I backed off the gas again, and tonight it also made the service engine soon light come on so I decided to pull over and pull the codes, and what it came up with was the following:
DTC P0372 IC 24X Reference Circuit Missing Pulses (Current)
DTC P1611 Loss of CVRTD Serial Data (Current)
Now this being my first cadillac Im not exactly sure about the codes, but tomorrow I'm considering checking the spark plugs to see if the ACDelco one's were used since the previous owner mentioned them being replaced, but would this cause this issue?
On a side note, I posted a separate thread a few weeks ago about a turn signal issue, and haven't had a lot of time to explore the issue. But today I had some free time and I decided to dig into this issue and explore possible problems. I checked all the fuses that are related to the turn signals and all are fine, I also checked all of the grounds and no problems there. I also removed the front headlight to check the front socket for corrosion and it looks brand new, along with the back. Now I know I mentioned this in a previous thread but the issue Im having is the right side turn signal do not work when actived from the turn signal switch or the hazard light switch. The left side works with no problems.
While looking through the car and trying to explore possible issues I was under the driver side dash and found a plug that was just hanging and not plugged into anything, I looked around for about 2 hours to figure our where this plug went and nothing....... So I was hoping that you guys might be able to give me some input, Im not positive but I'm wondering if this is related to the turn signal issue. Now the plug I found is blue, with a blue/white wire and a light grey wire.
Also note on the plug it says 3 PED if this helps at all, I have looked through my service manual I bought online and could find nothing that helps me with this so hopefully someone will know where this goes.
