97 neon sohc. the idle has been going crazy lately and i think i know why. The alarm and remote start was probably shorting out and throwing the entire computer/ignition system out of wack. Maybe I'm wrong but it seems to have fixed it. It was like the computer could never relearn it's parameters and it kept trying, making the computer go crazy all the time. maybe I'm wrong . what do you think? hey, after 10 years, who needs an alarm? I would suggest pulling it out for any electical troubleshooting problems.

 

Well If its fixed now, yea that was probably the problem.I had an o2 sensor wire resting on exhaust manifold one time, and the car did not like that one bit.
