Truck pulsing after spark plug and wires changed
Like the title say after i changed the spark plug and wires in my 08 i drove it and at idle if it sits long enough it will start pulsing every few seconds. The truck shakes a little and the RPMs drop a bit then go back to normal. I used Ac delco iridium spark plugs, with MSD 8.5mm wires for a 99-07 truck. Could the wires be the problem although i wouldn't think it would be? I know all spark plugs were locked down just right. What do yall think could be up? Is the computer learning the new thicker wires? Idk but in advance thanks!

i had a bunch of problems with MSD wires.. i got the cheapest ones the parts house had and no more problems..
i even got MSD to replace 4 of them and still no worky..
put your stock ones back on and see what happens.
