Default misfires at idle......arrrrghhh

Ok number 1 and 3 get many missfires at idle....then suddenly stop for a second and start over with the missfires...sometimes they get exactly the same amount. Did compression check and all drivers side cyls were at 180. No smoke...no overheating...no ticking. I;m at wits end here. Bought new plugs...swapped wires..coils...checked connections at all injectors and coil packs. What else could this be? They seem to mostly disappear after 1500 rpms. Also tried another maf. I dunno what else to try..no codes are being set. I even swapped pcm to no avail

Be more specific on your mods and what exactly is many misfires. Misfires are normal on the LS1 to a certain extent. Is your car running badly, whats the story..

My 1 and 3 do the same thing. Its not bad enough to worry about. It usually about 2 or 3. I also have a half dead 8 and I dont know why <img src="images/icons/confused.gif" border="0">

Many misfires as in 65-75 before it starts over at zero. Stock engine so I am now thinking its wiring or cps....will look closer at the cps wiring tonight
