Engine Problem
 

My 88 toyota pick up is having engine trouble, i was wondering if you guys could help me out with any info. When i start the truck it seems to be ok but then a few seconds after that the idle gets really low, and shutters a bit, and then when i try to hit the gas the truck just seems to stall out. When i start it and let it run it only runs for about a minute or so and then stalls out. I need info, any is very appreciated, thanks guys.

Whens the last time you replaced the spark plugs, wires, cap and rotor?
Cap'n

cold start injector.....

well i havent replaced all of those yet but have looked befor to check them out, and they seemed ok about a month or two ago, and as for the cold start injector, what could that be? im not sure.
