Default random misfire driving me crazy!!! lol

- okay so i checked and made sure i had power to all injectors with a noid light.... worked great

- listened to each injector with a screwdriver.....all sound exactly the same even with applied throttle

- unplugged each injector one at a time, each time i unplugged it it sounded worst except on injector 1!!!!! but you can clearly hear injector 1 firing

- did a compression test on all cylinders, got 155- 160 psi for all even cylinder 1.

- checked spark from the distributor on each cylinder.... all spark.

- swapped spark plugs on cylinder 1 with 2...nothing changed....( unplugging injector 1 did nothing, but the rest made it worst like before)

any help guys??? im at a lost.... i have a good signal going to injectors, good compression, good spark, and the injectors sound like there firing fine...

Sounds like you need to move that injector to a new cylinder, see if the mis moves with it.

If you are getting no rpm drop on cylinder #1, then that cylinder is dead. try swapping injectors.
