[QUOTE=ign 5;11821314]Hi everyone, Still pretty dang sure nothing in there. I used the camera, and saw nothing. Another thing is strang it ihas happened to more then 1 cylinder... And it something was bouncing around in there, wouldn't it go out the exhaust by now?

A 4g63 ingested a throttle plate screw and it took out three cylinders. It sounds impossible but I know it happened. The car was the personal driver of a well know shop owner and he reported the incident here.

And it something was bouncing around in there, wouldn't it go out the exhaust by now? I decided to check timing, cam and crank side, both spot on, so that is out..cannot be timing. Also, I put 6 gallons of 100 in and so far about 100 miles without a hiccup. It just has to be octane, just the tune, Has to be. I will attempt to go to tuner again today.

I agree, it for sure looks like something is hitting it, I still might attempt the seafoam while waiting for my tune, but runes good on 6 gals on 100. no problems. I will see tuners opinion also.

I will keep you all posted! thanks.

Look, we're being objective here and trying to save you a lot of money. For the love of god, stop driving the car. NO! A tune will not put marks on a ****ing spark plug. NO! Bad gas will not mark the crap out of a spark plug. NO! A piston hitting a plug will not make it look like that. You have something in there that is beating the **** out of your plugs, pistons, and probably cylinder walls. If "it" has exited out of the exhaust port, then you probably also killed the turbo.
Please, please, please, stop driving the car until you can get it fixed.

If you are going to continue to drive it the way it is then we really can't do much else for you.
