Why do I have to push down on the gas when I start my 1994 Mazda B3000/ Ford...
...Ranger when its very cold outside? When I start my truck in the morning or after it sits for a period of time, i have to give it gas and leave my foot on the gas for a few minutes (sometimes longer depending on temperature) If I let off the gas when first started, the truck stalls out. after a while if i let off, it bogs right down and growls, then jumps up to 1500 to 2000 rpms and again and again until i control with my foot again. Any help would be greatly appreciated
