Hi all

I got a yellow check engine so I m wondering what is the trouble. My car is near 60000 miles , I don t have the cold start probleme, I was also on a near empty gas tank so I wondering if water in gas is a option.

I start my car today, it got a bad idle, give a touch to the accelerator and it fix temporary.
So I drive to the supermarket without hard acceleration nothing over 3500 rpm and I got a yellow check engine when I was at a steady 60mph. The codes are as follow in this order
P273d - p2772 - p2d52 - p2dcc

From my researsh the code say
P273d= ignition coil cyl 1
P2772= miss fire cyl 1
P2d52= super knock
P2dcc= super knock cyl 3

This was what I find on the forum, I can t tell you everything is good.
So my question is this, what should I look to fix this first?
Does it sound familiar?

 

I STILL GET THE SAME code, everything point out cyl 1 (coil) so I switch the coil 1 to the coil 4. Nothing change , so I decide to switch plug 1 to another and finally I found one big probleme that seem to have not made any damage. The porcelain near the electrode is broken but still hold to the sparkplug between the electrode and the ground. It goes back and forth on the electrode. So I will change all 4 sparkplugs to new one and the probleme will be fix hopefully.

The plug was ngk dilkr8b6 laser iridium with near 7000km only. I will put picture when I will get the new ones.

any of you can recomende a good plug? What can have happen to break the porcelain? No physical damage.
