ok so the other day i started having constant misfires, and they after they got realllly bad and are still horrible... i have a 99 T/A Ls1
I put in NGK TR-55, New 10.2MM RPM Speed wires. Never heard of these before so i dont know how good they are but they dont fit on the plug itself very well... Made sure they were all gapped about a month ago. I made sure all the wires are properly connected, re checked the spark plug gap. i have the exhaust off and dumping around the middle of the car. idk if that culd be an issue
I was watching the misfires live feed on this scanner and it was only cylinder 2 and 7. 7 was the worse. i swapped around coils to see if it was coils but it was still 2, and 7. i got a couple misfires today also on cylinder 6 and one misfire on 8 but 7 and 2 are still the main ones, is there any other recommendations? an its weird. sumthing has to be up. when i first start driving off a green light it mis fires real bad and thru second and when i stomp on it u can feel it chug and pop as its accelerating hard, but then sometimes it all just completely goes away and drives soooo smooth. then happens agai nonce i finish driving and turn off the car.. i wonder if the wires i got are shit or sumthing?
