Okay so when I had the codes read it came out to knock sensor and IAC malfunction Idle Air Control. So one day my mechanic saw what it did. When I put the car in P or N the car revs to like 2k rpms. He messed with adjustment screw to lower rpms but now when I start the car it dies right after. It cranks sexy but then it turns. When I crank it I have to give it gas for it not to die and hold it there. I keep my right foot on the gas so it wont die and brake with my left. I fell like im driving a manual haha even tho its a automatic. I have the only manumatic transmission in the world.

Increase the set idle and get your knock sensor and idle air control fixed or replaced as soon as possible.

The ISC is a open loop system. If it dies the car wont know. You get the Idle Control code from the ecu if the car can't keep the idle at its target for whatever reason (vac leak, ISC motor dead, fuel trims out of wack, BISS adjusted incorrectly, FIAV broken, still in open loop warmup) The BISS should be set 1.25-2 turns out from soft bottom, and make sure your coolant is topped off and let the car warm up to 190*, if the idle is high, check for vacuum leaks. If none are present, and you are running aftermarket injectors make sure your idle fuel trims and mid fuel trims at 0. If you are running stock injectors, or you know for sure your fuel trims are perfect, test your ISC motor http://dmtalon.v8eaters.com/ISC.html

At this point you can probably suspect the FIAV valve is bad, heres my walkthrough to fixing it. http://www.dsmtuners.com/forums/bolt-te ... t151720501

Knock sensor wont mess with you idle, it will make the car run as slow as a Honda Del Sol though. Pretty easy to tell when its dead if, it has goo leaking out of it, its dead, if not, check the electrical to it to make sure its fine before replacing it to find out you still have issues because it was electrical in the first place.
