car cuts off in idle??
ok so my car takes FOREVER to crank up and i have to keep mashing the gas to crank it up.. and when it does crank up it sounds like its skipping but i just changed spark plugs and wires...
i have to keep the rpms up or it will shut off? i dunno wtf is wrong with it now!

Check you IAC Cable hookup, the IAC should be bolted to your throttle body somewhere. I left mine undone after cleaning one day and it sounds like the same thing. Or could just be the sensor gone bad, or lots of other things i dont know much about cars.

Check your fuel pressure, Vac leaks and IAC.

Controls how much air gets to your engine when you are not mashing the gas. Basically, some gunk starts closing the small clearances between the IAC valve edge and the solenoid stuff which slows/stops the valve from working, which in some cases will stop working in the closed position, and will not deliver the necessary amounts of air, causing stumbling and stuff, eventually turning off the car, if not mashing the gas around idle rpm. |

Yeah when you pull that off the air is not drawn from your intake, so the maf doesn't read any air. Your car needs air measured by the maf.
