update on this issue. no more clatering at 2800 solved that issue created another. i have not had much time to work on the boxster for a while, but i had taken the apart the valve cover on bank 1,2,3 a couple of months ago and found what i took to be 4 colapsed lifters (tappets), 3 exhausts and 1 intake. I purchased a new set for that whole side, last week i had time to dedicate to reassembly, put it all back together it started once in the beginning and for two days after couldn't get that thing to start for nothing. it would shake and sputter and pop but would not start. by that time spark plugs were fouled, changed plugs tried again a few more times, nothing. next day checked plugs, they were fine, tried again until it started but it would backfire and pop for about a minute then it leveled off and sounded good but when i take my foot off the gas it would die. drained fuel put new fuel in (fuel had been in since february) checked timing again, timing is on on both sides, removed MAF cleaned it put it back in it starts, sounds good at 1000 rpm and above, take foot off gas and rpms dive and motor shakes and sputters, if i slowly give it gas it will pop or backfire and then levels off above 1000 rpm. code reader keeps giving me P0300 P0306,305,304, cleared them a few times but the reader pick them back up a minute or so after i start. swapped the coils to other side, recleaned MAF still get the same P0300 for bank 4,5,6, and the check engine light comes on and starts to flash
anybody have any thoughts as to what it might be? the misfires are from the side i did not work on.
