Sluggish acceleration when cold

[seligman2]

My 96 Tacoma, if not driven for a couple days, will be extremely sluggish in accelerating when you first start out, particularly on hills. After a few minutes and a mile or so, it will take off like a rocket without the road or my driving changing one bit. In other words, it might be laboring in 3rd gear at about 30-35 MPH, then within a few seconds I'm suddenly doing 40 MPH while my foot hasn't moved any on the gas pedal, nor has the grade of the road changed any. This problem is worse in cold weather. Is this a sign of clogged fuel injectors?

Before getting into other stuff, have you checked the obvious? Air filer clean? No leaking hoses? Oil quality ok, adequate level? Any new or abnormal engine sounds? Sub-standard fuel? If these are ok, get back to me.

Sounds to me like you just need to let the engine come up to normal operating temp before you run it hard.
