Ok, thanks. I've already ruled out the coil by swapping, so is there any trick to swapping injectors? Like how to not drop bits into the cylinder or something scary like that?
For the solenoid. Do I unplug it tonight and run it like that a couple days or do I wait till it's running bad and then unplug it to see if it fixes it (i.e. will it hurt to run it while unplugged).
I tried the unplugging when it happened before, but when it stopped I wasn't sure because if I turned the car off, reconnected it and re-started or simply plugged it back in it wasn't missing anymore.
