Also, make sure your not running bosch platinum's. They have resistors in the plugs which would mean a double whammy! Also, check your coolant temp sensor, its located at the back of the head near the firewall. Mine actually vibrated nearly off so it was arcing a contact on and off. Good Luck!

"It cannot be emphasized too strongly or too often that this great nation was founded not by religionists, but by Christians; not on religion, but on the Gospel of Jesus Christ. For that reason alone, people of other faiths have been afforded freedom of worship here." Patrick Henry 1776
