I took my truck to shop cuz no power. it starts idles good for about five min the throtle body starts sucking air like a damn jet engine then get so bad im scared to keep in on. getting no codes thrown out. oh ya the shop said it was my ignition coil thats why i was getting codes at first and my cat was bad. cut cat out and replaced ignition coil. no better it will idle fine for a few the start acting up. i tried to drive it, boggs down like crazy then i can floor it and it will get crazy power then bogg down again. thinking it might be a MAS sensor oh whatever but i looked that up and it doesnt have one. anyways im at a loss any suggestions would be apreciated.

 

I don't know for sure what you mean by MAS - most Dakotas are old enough, they're SD (Speed Density), and use MAP (Manifold Absolute Pressure) sensor. Newest ones may be MAF (Mass Air Flow).

How about the Intake Air Control (IAC)?
