I recently had to change the Idle air valve for the surging RPM problem. Got it changed and was running smoothly. I noticed the accelerator cable casing was splitting out so I ordered a new one to replace it. Now when I start the car it jumps to 5000 RPM and stays there. I have adjust the cable so it has slack and even unhooked it and still have the same problem. Any ideas?

 

Your throttle may be stuck open because you tightened the intake hose too much. Loosen the connection right before the throttle body and see if that goes away. I did that when I cleaned out my idle valve the first time.
