replacing coil packs what should I get.
I want to replace my coil packs (all of them) I'm on a budget and want something good but affordable thinking around $250 any suggestions. I have found many on ebay ranging from 133 all the way to 600. Thanks in advance.

Got it, well good luck. Why not just get new LS1 packs then? For sale section, supporting vendor, parts car? They are good coils overall and yours lasted 150k...

Look at this -
If your car is tuned be sure to not exceed about 5 milliseconds on dwell. Check with your tuner. You can go on up to 6 ms or a little better but at that point I would widen the plug gap about .002 - .005 to get a better burn. Higher dwell times above approximately 5 ms create more heat and shortens the life of the coil. My opinion it's only justified for high boost and short duration racing bursts. Your millage may vary

there are lots of things that can cause a misfire other than the coils so I would suggest finding the root of the problem before you start throwing money and parts at it... the oem coils rarely fail and they are more than adequate for most people's mods... the truck coils with heat sinks and ls2/3/7 style coils are better than the ls1 but probably not needed in your case but if you do end up getting those make sure to have your tuner adjust the dwell... so I agree with the posts above, but if you really need to spend $600 on some coils send me some money and I can paint some red for you (I'm kidding obviously

I agree there are man things that can cause a random mis-fire code---Especially on an older car or a car with mods
The coils on LS engines rarely fail---I have installed the pricey MSD coil and a C5 and after a dyno run there was NO HP or TQ gain-----
You 1st need to identify if fact you have a "real mis fire" or a "false mis fire"
If you can hear or feel a misfire then it is real
BUT it you cannot hear or feel a mis fire then it is a FALSE MIS FIRE
Many mods can cause a false mis fire----LT headers--cams---Stall converter--aftermarket clutch---or even many miles or age----These false misfires are VERY common and can be erased with proper tuning

Given that the computer declares misfires based upon hiccups in what its seeing from the crank position sensor the only false misfires would be due to issues with that sensor and/or the wiring to it. You generally don't see false misfires.
I agree that changing the coils aren't likely going to make your misfires go away. Change them if you wish but do so knowing that it's most likely a waste of $ and time.
