Hey all, I’ve got a 1998 B4000 4x4 with the 5 speed manual, I’ve been battling an issue since I bought the truck last winter, whenever I start it on cold start it starts to bog? But It usually doesn’t stall out unless it’s below 0 Celsius, I’ve done most of the common fixes like the PCV, running injector cleaner, spark plugs and wires. I can’t for the life of me figure it out, any help would be appreciated
