ok im really in need of help here my 2002 ws6 is a daily driver and my wife is starting her new job soon so i cant drive hers to work anymore,
ok here goes
ive got a sound a code and loss of power and it shakes all through the pedal and shifter.
sound is like a rattle/knock this is in idle and speeds up with rpm
code is p0300
what i have done,
put 93 in it ( i ran 87 for a month or so bc of $)
pulled valve covers, springs, and everything there looks ok to me,
pulled plugs, 2 of them were extremely more worn than the others, i cant remember now which cylinders they were but i know they fire right after each other in the sequence,
so i replaced the plugs, and finnaly put my long tubes on that have been sitting in the garage for a year,
anyway started car up after everything was put back together and the sound is still there, drove it arround the block and noticed the lack of power,
so that is what i have done, please if some of you ls1 gods out there got something i can do, or if you know a thread that can point me in the right direction please let me know thanks in advance

Bump for suggestions

P0300 is "Random multiple misfire."

Most likely causes, in my experience, are bad plugs and/or wires, or a blown coil.

Is their any of things wrong that your noticing? My p0300 was from my tci ssh 3600 stall. Could be plugs and wires.
