What should I do about spark plug tips breaking off in combustion chamber?

[DORIMON]

The past few days I've been trying to figure out why my car has been hesitating when I would go WOT for 7psi. At 1st I thought it was a fuel problem so I changed my fuel filter and then also going back to my initial 94 octane over my sudden change to 93. I also did an oil change to just get rid of the 1st 1K miles from having the redtop SR in my car. Also tried fuel injector cleaner and adjusted my timing a little. Checked my turbo for leaks as well as piping and vacuum leaks. Also cleaned throttle body and checked MAFS. After all this, nothing helped, so I decide to pull the plugs and see how they look. Well, 2 out of 4 plugs seem to show pre-ignition according to PDM-Racing's spark plug reading page. (http://pdm-racing.com/features/plugs.html) The electrodes are damaged as well as the copper tips have been broken off. I'm thinking accidental tapping of the spark plug during installation after my recent compression test may have changed the gap then causing them to break off somehow. Now my questions are, what can I do to verify if the tips are still in the chambers or not? I'm planning on trying to use my shop-vac and some small vacuum hose to try to suck the tips out, but if I can't get them out, is there a chance they may have burned up? Are the tips more than enough to cause cylinder damage? I can't really come up with a straight answer for these questions after searching. Someone please point me in the right direction. Thanks.

MORE FUEL LESS TIMING!!!!!!!!! Most likely the tips have blown out the exhasut by now. You really need to tune that isht or you are going to blow your motor.

how about trying some better spark plugs too.

the tips are gone. melted away by detonation. No need to worry about them anymore. And the plugs you were using are fine as long as they are in the 7-8 heat range. NGK R's are perfect for that engine. You have bigger problems. you need to find out why you are running lean at only 7psi. Do you have an upgraded fuel pump? Is your ecu stock or re-mapped?

Rough idle is gone and I'm hitting stock boost easily with no hesitation. Before I took it out for a drive, I tried to use my shop-vac to get the tips but I don't think they were in there. I tried to blow in there and see if I could hear them rattling around, but nothing. So I guess they did just burn up. Anyway, I think I'll go for the 7 range. I totally forgot about that after I just replaced the plugs with the same ones (BCPR6E-11), the same ones HT sent methe 1st time with their tune-up kit (http://srswap.com/shopexd.asp?id=268). I do have a Walbro 255 and stock ECU. I truly think it was from accidentally closing the gap on the plugs by accidentally tapping them while trying to seat them correctly when they were being reinstalled after my compression test. If not that, it could be from a time when I ran the car hard with a little under 1/4 tank of gas, not sure if that did it. I always assumed I was running rich. Maybe it was my timing. Anyway, thanks guys for the help. I think I'll recheck the plugs after a few more drives and post again if anything is wrong.
