SuBrat84 Posted March 27, 2007 Share Posted March 27, 2007 So, long story short here we are with Courtneys SECOND motor swap. Everything went more or less flawless. Started it up and with-in 30 seconds it threw P1507 Idle Control System Malfunction (Fail Safe) I don't even know what that means. Everything worked fine before (Except the ticking.) Right before she brought me the car she sprayed the engine bay out and it threw a knock sensor code.. but that went away once the car was dry. So then I swapped the motor.. and now here I am. I am going to call CCR tomarrow and see what they think. (If I don't get any good ideas here first.) I'm going to cry. I'm starting to feel like a failure or something.. even though the first motor wasnt my fault. Link to comment Share on other sites More sharing options...

SuBrat84 Posted March 28, 2007 Author Share Posted March 28, 2007 It ended up being a dirty sensor in the intake manifold. Problem solved, runs great. Link to comment Share on other sites More sharing options...
