those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Check the resistance on the coil. the (+) (-) side should be about 10 Ohms resistance and the part that goes out of the coil should be 1-2 ohms resistance. Get yourself an ohmmeter and check it. best way to check is to figure out what wire runs from the computer to the coil and follow the wiring all the way to the coil making sure theres no rips or shorts. If there isnt, then I would splice into the two wires and run two new wires over to the coil. If it still doesnt have spark then its a faulty computer and should be replaced. Good luck
