GT Bogs Down HELP!

2002 Grand Prix GT 3.8 NA, 91K miles

It was bogging down and just not having any balls to it when I put it over 50% acceleration, now it's getting worse, eventually check engine light went on/off then it just was on as soon as I started the car.

The error code was P0300 Random/Multiple Misfires

So I got new spark plugs, autolite 606 iridiums, gapped at .060, and MSD 8.5 Spark plug wires (I know I know, just put that aside ok)

so I put everything in and she still bogs down, worse than before but rev it up as high as I want the check engine light refuses to come on.

Is this

1. Clogged catalytic converter
2. 02 sensor
3.throttle position sensor

Please help me I am really frustrated
 


took it in and got it checked out it was indeed a clogged converter, I had them fix it for free under case # 05551

They told me that my wheel bearing hubs needed to be replaced, as there was movement in them, they quoted me $950! I told them thanks but no thanks. I found some with lifetime warranties for 42 bucks free shipping.

Well thanks everybody for . . .all your . . .yeah . .nevermind :th_laugh-lol2:
