my scanner shows it as idle air control over speed malfunction.check the idle air control sensor to see if its dirty or has a loose connection.if its bad they're $35.99 at auto zone.

when I start my truck it won't idle if I put the gas pedal to the floor the engine rpm revs up then goes right down and then revs up and down exhaust blows out strong fumes If I unplug the maf sensor the engine runs fine but won't idle I did replace the aic sensor and the maf sensor could I have a defective maf sensor

anything is possible with todays technology as far as getting a bad sensor.did you clean the carbon out when you changed the iac?
