    What the heck is happening?

    Hey all,

    My issue started mid winter, it was suuuuper cold, and as i was on the on ramp leaving for work their was a slight stutter almost like the tires were slipping slightly then the check engine light started flashing, it stopped and was fine seconds after(i figured my car didn't have time to heat up). The next time it happened was a month or more later at the same spot on the on ramp while it was raining. Then the 3rd time it happened it was also on the on ramp but regular conditions.

    Today is the 4th time is has happened on the on ramp, but this time it happened multiple times during my drive as well(an hour+ drive), and on my way home. It SEEMED as if it was happening more often when i was accelerating quickly but i can't be certain.

    Any Idea what this could be?

    EDIT: I have a 2006 3.6l cts with about 110,00 miles

    A flashing CEL is signaling a severe misfire being detected. Have you checked your oil level at all recently? I would see if you can take it somewhere that can scan the codes. There just might be a history code stored that will tell you which cylinder was misfiring, that will help narrow down the culprit. Could be a coil, spark plug, fuel injector, and worst case is a stretched timing chain (not good!).

    .

    Yes, Same thing happened to me about a month ago, swapped out spark plugs, cleared the codes and it works fine now. It could be a coil pack as well.

    I'd just stay away from that off ramp......lol... sometimes humour helps, not with the car but with the situation. Take it to get the codes read, and post them here, maybe someone can help you out.

    Re: What the heck is happening?

    lmao.. that ramp doesn't seem to be a good place.. my logic tells me that when your putting a good load on the engine such as going up the ramp... its causing a misfire. which then would lead me to believe you should read codes and change plugs. Coils could be cracking due to age and need replaced.

    if it was a stretched timingchain/ worn guides.. it would be running rough even at idle and all through the rpm range.

    Not true, if it's just a little stretched it may only exhibit symptoms under heavy load.

    Re: What the heck is happening?

    I don't buy that. theres always a load on the chain whenever the car is running.. whether its stretched a little or a lot... its always gonna be pulling against the chain and running in an off timed situation.

    but I may be wrong.

    Re: What the heck is happening?

    When under a light load the chain may stay on time just fine, when under heavy load it can skip if it's stretched.

    Think of a bike with a loose chain, peddle slow and you might be OK, start peddling faster and it's probably gonna start jumping.

    I've dealt with stretched timing chain and severely worn guides before on the 3.6 in cts.. a stretched chain or worn guides doesn't cause intermittent issues. once an issue/ always an issue unless resolved. make sure to let us know what you find OP..

    Unplug your battery both terminals for an hour.
