Intermittent Low Idle

3.Slow V6 Manual.
  • *sometimes* While coasting to a stop sign with the clutch in, my engine will drop to 500 rpm, shudder slightly, and then rev back up to 800-1000rpm idle usually when I come to a full stop.
  • I changed the air filter and did plugs and wires--no change.
  • No engine codes, I checked bulb operation
Any ideas?

Thanks guys.

Year? Have you tried cleaning the throttle body and IAC as well as the IAC passages?

My bad! It's a 99.
I'll clean the IAC and report back.
