well on my way home from the track last week i hit a stop light and my car started shaking. sounded like it wanted to die but it would juss sit and iddle at 500 rpm instead of 1k. i would give it gas and it would stutter then revv up.. i had to get home so i kept going.. once in gear the car ran fine. didnt seem like i lost any power or anything. but at every stop it would hesitate and idle very low. got home parked it. 2 days later i started it.. started fine. ran fine all the way to work no problem.. then i started having problems again on the way back. same thing idles at 500. but it doesnt die..

i started the car back up again tonite and started fine. but once its warm it idles very low again.. what do you guys think the problem is?

 

that sir is your cylinders misfiring due to 1. bad spark plug wires 2. bad spark plugs or 3. bad distributer. I recently had the same thing happen it starts to get worse.

 

One would think it would do it all the time if it was one of those things... It is a distributorless ignition, so number 3 is out.

maroman, on the Mustang I used to have, you could unplug the IAC and it would idle right at 500 instead of the 800-900 rpms it normally does. Possible that the IAC is faulted. You might check that out by unplugging it and seeing if anything changes.

 

That's an interesting problem, I would say points, but my knowledge is in old school stuff with carbs, so I'm out on this one.
