A challenging question for any mechanic?

I have a GMC Sonoma 2.2 4 cyl. I have a hard one to answer it has stumped me and alot of mechanics even certified gm mechanics. The last 2 years every winter my truck hesitates while trying to advance speed or when I give it more rpms in every gear (stick shift). When it hesitates almost like its missing I can feel clunking. I have changed plugs and wires twice in 2 years, today I put 2 new coil packs on, I change my fuel filter 3 times a year, I did a fuel pressure check it was good, I put 2 new o2 sensors on, changed catalytic convertor, There is no check engine light on. When its real cold I cant or can barely start truck. When it was in the below weather I tried to start it so many times that I fried the starter ( 1 year old) I put a little starting fluid in and it blew my plastic in pieces that connects air filter and throttle body. I have not done a compression check. Sometimes when I am idling and revin it up the engine bogs out when its cold. Last winter it wasnt as bad but still a problem as soon as the weather got warm the truck was fine. The truck idles normal
