i wanted to test my coils to make sure im getting enough voltage. i had a couple tech guys tell me that you can go to napa or somewhere and buy an inline volt reader or something to test the voltage and that there only like $5. anyone hear of this or know what there talking about?

or the test light style

or the screw style with graduations marked in kilovolts

they all go on the secondary side and if you can change plug wires, you can use these tools.

pull the plug, then connect the plug wire back to the plug then put your tongue on the two sark plug electrodes. If you die its getting enough. Get someone you dont like alot to do to it. Perfect suicide. "Guy was changing my plugs and killed himself." J/K

lol....seriously i need to test this as 2 different tech guys both suggested my coils could be bad is why my nitrous doesnt work right, they tested everything else.

Easy way to "test" the coils is to swap them to different positions and see if the problem follows.

BTW: never seen one go bad, plus there are LS1 making ~1000+ hp on the stock ones

there is nothing to swap, i havent the slightest clue where one could be bad. i get a mult cyclinder misfire even after i got the car tuned but it could still just be the cam i dont know.

cant help you on the tester but whats the spark plug gap? have you tried tightening it up by 5 or 10 thousandths?
