ya ive had the same problem before, not on my tacoma. but i ended up burning a plug wire (or a bad spark plug will do it to)
other things would be to clean the MAF, most likely not but also could be TPS, also could be a plugged cat, giving it way to much back pressure.
id definitely go with the spark plugs first. if you haven't changed them in days might as well just buy new ones and do it anyways.
