so after all the racing, nitrous and serious dd, she's randomly misfiring, P0300. problem's been going on for a while now but progressively getting worse. she tends to lean out at idle often hitting 17 on the a/f and she backs way off the spark adavance almost to the point of dying out until it kicks back in. with the a/f often richening up to 13.6 where it tends to return to stoich at around 14.7ish where she bounces between low 14s and high 15s. been trying to diagnose the problem until the misfire code. so now i got a few parts i'll be replacing to find my solution, however i am having a hard time finding a new ignition coil pack. i'll be replacing my injectors and the tb and getting a re-tune in the process. so can anyone point me in the direction of an icp for the L61?

 

is it all your cylinders that are misfiring. if its only 1 or 2, try swapping that icp with one that isn't misfiring and see if the misfires travel with the icp. that would save you from buying random parts that may or may not fix the problem. this way you know if its that or not.

 

i'm replacing the injectors and tb because it's been a project for a while now, and it'll simply be for my piece of mind. as for the icp i don't have one to swap it out with. not to mention i'm looking to replace the original one anyway. i've driven this car hard and i've done a damn good job maintaining her. my issuse now is not uncommon however it is not easily diagnosed.

 

you running bkr7e? if so change them out. they arnt that much. it could be a easy fix with just plugs.

 

runing stockers now actually, the iridium delcos. they've been in for about 20k third set. cars sitting on 77k and this engine has 51k on it after 25 bottles of boost juice and the original trifecta tune.......so say 77k anyway, given abuse.
