3rd cylinder misfire...I would def check plugs and wires. Also if you have an AFR gauge how were the numbers and do a compression check as well on all cylinders.
I was on my way to work today, doing about 40 on the ramp to get on the freeway. When i accelerated under boost, i felt the car hesitate like it was bogging on me so i let off. Right after i got a code P0303, maybe the plugs?

Check your plugs first to see what condition each one is in. Its very simple to take the spark plugs out and put back in. Just make sure everything goes back the way it was....VERY IMPORTANT!!!

Sounds like what i was having where the spark was being blown out. Change the plugs.

If those doesn't work, check the head light fluids. Those could be a ish to do. good luck :p

needs new tube seals. plug #3 looks like it ran a little hotter than the rest. and youre missing the tip of spark plug #4. lol
Yeah #4 is missing the tip, wondered how that happened. Tube seals are only sold only at dealer? or can i get them from pepboys.

you can get them at your local store...they come with the valve cover gasket kit. i dont think i payed more then $15 for my v6 when i changed everything.
If the tip of #4 is missing it could have burned up from being so hot. When the tuner killed my old motor on the dyno, all 4 plugs were toasted, no electrode or anything left, it looked like a screw.
It might be as simple as changing the plugs and/or coils. When the car was running good did it normally run rich? My car ran rich like 12.8-13.5 while in vacuum and I killed a set of NKG BPR7ES's in about 150 miles. I was misfiring, the car wouldnt idle, at one point it wouldnt even start, new plugs, all problems went away. You may want to also try going down one level to a colder plug too.

Thanks for the info guys, Ill pick up the gasket this week. Stewi the car did run rich, 12.4-14.3. I had these current plugs for about 2+ years or so. In the last couple months, i did notice misfiring, but just shock it off. I guess this was the issue all along then. Yeah ill try 1 level down plugs aswell. Also its better to replace all 4 plugs? compared to just 1 or 2?

2 years is a long time for plugs in a turbo car. Replace them with a set of NGK plugs one step colder and correctly gapped.
7g for life!
Currently im using the NGK colder Plugs BKR7E, So go down to the BKR8E? The gap is .039 -.043 correct?
Since were on this topic, how many miles do you guys usually replace your plugs?
