^I was gonna recomend that too...my gauge was busted so I put a pressure gauge to get a quick reading and I was running 28psi and bumped it up to 48 and it starts ALOT better. A quick test someone told me to try once was to take off your intake piping and plug the holes inside the throttle body one at a time...if it idles right when you plug up the top one I believe it's the IACV if the bottom hole corrects the idle then it's the fast idle control sol??<----forget what it's called exactly but its the sensor under the throttlebody...
