The truck's engine has always been easy to start but lately, at odd times, it seems not to turn over. So far, it always starts cold, the first start of the day, then after sitting a while(while shopping for instance), it sometimes takes 3 tries to get it started. This doesn't happen all the time, maybe 1 in 6 starts. It has a pretty new battery (1 year old).
I did use a gasoline additive twice, one bottle for each full tank. After the first tank with the additive was burned, I filled it up again with no additive. Then the next tank I added another bottle to the full tank, as directed. I have since filled up the tank again. Do you think the additive may have loosened some gunk that's getting in the way now?
