hey could fuel injector cleaner or fuel system cleaner cause flooded engines? cuz i just put some in and I heard that it may dry something in the injector and cause it to spray hecka juice.

No, should be OK, however they don't generally help much (at cleaning injectors).

Did the car flood after doing this? Had it been flooding at all beforehand?

ya flooded after putting a new bottle in, but just realized that my grampa of a brother pumped the gas while trying to start it up. it's all good now, i just need to fix my timing and i'll be ready for cruisin.. o btw who's going to CMI?

ohhh, yeah, thats a nono. I did that on my first FC.

You should probably start another thread if you're wondering about CMI, dunno if anyone is gonna look in here for that.
