I would have told them take the coil charge and kindly place it where it belonged. Thats why they charge so much for simple procedures, so that if they break something, they can fix it with no cost to the customer. I dont think thats right that they charged you for the part that they broke. Ive been putting the spark plug change off. I havent been driving my truck at all though because I have my work truck. I counted up the miles for the past year, and I ended up with 2000 miles. LMAO. gotta love it.

Anyways... I havent noticed any white smoke on cold starts.
