I searched the threads and couldn't find anything on injector issues (I think I broke my search function) so this might be beating a dead horse :spank: but I'm taking the short route and asking...It's been cold in SC and my starts have been taking 1-2 seconds longer than straight up like normal. Also, this morning my truck was puffing a little bit of white smoke for a minute or two. Also, mileage has been slowly dropping. Is this an injector issue and I should have them tested or is it just winter time drag on the truck? My truck has 90K miles on it. Any tips are welcome. Thanks.
