OK, truck ran fine when i bought it four days ago, now when i try to start it, i have to hold gas pedal to the floor. when it finally starts it idles extremely rough. i can give it some gas and will run up to 1800 - 2000 rpm's and smooth out but if i give it anymore gas the engine will bog down and try to stall. I checked all plugs, plug wires. Please help me!!! Someone said check the iac valve but i didnt think it would affect the engine at 2000 rpm's and cause it to bog down... what should i do?
