Sounds like your linkage at the throttle body is binding up causing it to stick open. Check linkage a throttle body and accelerator cable.
If that doesn't find the problem, put car on a scanner that does real time sensor data and check tps for out of adjustment, iac counts, and maf readings as your primary suspects. But check all the readings of the sensors to see what is going on.
Did you remove any grounds when you changed the intake, or unplugged any connectors that you might have forgot to plug back in.
If you don't know what sensor readings should be, pm me with your e-mail address and I'll send you the pdf file of "sensor readings and what they mean".
