SOURCE: 87 toyota 22R no spark
To check the Coil, pull the HT lead that comes from the coil to the dissy cap out of the dissy cap and hold close to the engine and with the ignition switch turned on earth the negative side of the coil. If there is no spark then the coil is the likely problem. If there is spark then check that the ignitor is recieving the signal from the pick-up (use an LED tester at the ignitor plug) the tester should blink as you crank the engine over. If the tester doesn't blink then check the output of the pick-up at the plug on the side of the dissy, if still no blink then check the pick-up clearance. If it blinks at the dissy and not at the ignitor the check the wires/plugs for breaks. If it blinks at the ignitor and there is still no spark then the ignitor is the likely fault.

At the cost of the igniter i recommend checking your pickup coil.( The 2 wire sensor in side of your distributor. The The igniter will not allow the coil to fire with out reference form the pickup coil. Coil has primary and secondary resistances. when the primary coil powers up and then pulses off, this cause a high voltage due to magnetic degeneration. Check the coils primary and secondary resitances along with the air gap in the pickup coil, and also check the resitances on the pickup coil. If i am right your igniter will be okay.Get a good manual for you truck, It will save you money down the road.
Toyota does not have at test proseger for the ingiter.
Also check the wires in between the pickup coil and the igniter.
I hope this helped.

It seems there is some kind of air entering the carburator where its not required to do so or the idling soleniod switch is malfunctioning, thus not allowing the air to enter for the engine to idle .
Also recheck the vaccum pipes if they are correctly refitted per the schematics under the hood.More over remove the idling switch and blow some air to the hole probabley theres some kind of obstruction over there .
