Rep Power: 0

Hey guys my car recently started to bog down and gearbox told me to clean my throttle body and IACV, my car doesn't do that anymore but after i cleaned everything out and put it back together i turned it on and when i press the gas pedal it will rev 3-5 times up to 1500 rpm and down. After 3-4 times it stops. This happens when i idle. And yes i did do the idle learn its idling perfect at 850 where i want it. ( When i cleaned the TB and IACV i didn't replace the gaskets i just used the same ones ).

Please if you can help do so. Thanks
