Hello Everyone,

Happy New Year. got a ?, but first a quick recap on this vehicle. I had a reoccurring fuel issue. After doing the pressure test, it appeared the fuel pressure regulator in a 1 year old filter was bad. I replaced it, and the pressure as well as the leak down test was perfect. The car ran great for the past 4 months except that the new filter squealed pretty bad at start ups, (worse when it was cold). The other day, I started it up after a few days of sitting, and after 20 seconds or so, it started to sputter and shake a good bit. Sounded and felt like a misfire. I did the scan and got the P03030 , 16687 code on cylinder #3. I looked up all the possible causes and remedies on this site, but I was wondering if anyone with more experience here could give me their opinion on where to start. I'd like to work it in an orderly fashion and not just start throwing money at her. I was thinking i'd just start by swapping the coil pack with another quick, then the plug. I can check the coil with meter while its out, too. Anyway, I appreciate any advice. Thank you. Mark PS, sorry for the long VCDS log. I forgot how to place it in its own window.

Hello to everyone,

Since you have a P0300, its a bit tricky but first swap the cylinder two and cylinder three coils, ensure that you mark the coils. If the misfire moves from three to two, then you have a coil problem.

If it does not move, pull out the spark plug from cylinder three and compare it with cylinder two spark plug, if you do not see anything then you may swap the plugs. If the misfire moves from three to two, then you have a spark plug problem.

If the misfire does not move from three to two, swap the injectors from cylinder three to cylinder two. If the misfire moves from three to two, then you have an injector problem.

if the misfire does not move, then you have to do a compression test on all the cylinders and see whether cylinder three does not have the lowest pressure.

Thanks for the advice Shade, but I may have found my issue. Pull the #3 coil pack , and this happened. I barely pulled on it. I'll be ordering 6 news ones tomorrow. Guess this makes it easier to diagnose the misfire problem. well, I can't get my pic to turn into a URL. I sure miss being able to just insert an image on forums Anyway, the coil pack just snapped in half
