Rough Idle - stalls -

Hello!

Plugs replaced - recently

However, sometimes she idles badly.... Tries to stall, sometimes stalls but turns back on just fine. No check engine no codes just plain bad idle.

sometimes coming to a complete stop she stalls again no check engine turns back on like nothing happen!


Any ideas?


Thanks

Have you had it scanned for error codes? Sometimes you will have faults present that do not necessarily throw CEL on the dash.. I would get it scanned if you haven't already and post any errors up here for us to see.

If I had to just "guess" I'd lead towards a bad Idle Actuator or voltage regulator..

Vacuum leak is a possibility as well. There are two large (1" ish) hoses leading from the bottom front of the intake plenums down underneath to the idle actuators. I just found the hose clamps on mine weren't even tightened down from the last person to work on it (not me).

However, these idle actuators are just as failure prone (if not more so) than throttle actuators and the old SMG pump motors.

Sounds to me like you may have a bad EKTP (Fuel Pump module). I would get the car scanned, and find someone has access to a autologic, do a tank leak test.

Same problem here. I'm leaning toward the issue being a bad cat converter though.
