Thanks for that! I didn't think it was likely serious, but as I have only 1 month left on the dealer warranty I thought I should check hereI get a little of that with my 2017, pretty sure it is normal for a straight 4 to do that, they are inherently unbalanced so there is a lot of shake when they are cold. I would bet yours is just shaking the catalytic converter or the heat shield.
Thanks for this. My next cold startup I will wait until the blue light goes off before any acceleration to check for your suggestions. The mid pipe flanges may be the culprit, as the sound does seem to come from under body somewhere. Thanks again.This could be normal as until the blue temp light turns off and the idle lowers the lifters do make a bit of a louder ticking noise than when the vehicle is warmed up. Also, there are these really dumb little like heat blanket patches riveted to the manifold covers and the rivets are known to rot out, could be one of those little blankets, I’ve pulled plenty out of the bottom of the early 3rd gen 3’a While doin oil changes. I would also check the muffler to midpipe flange as those donut gaskets do tend to lose some material.
