Engine cutting off on low rev

It happened to me twice before I changed my ignition coils... thought it was related to it.But now it did it again last week...
Here's what happen:

I drive on the highway at around 75 mph.
When I approach the off ramp, I push the clutch down and let my car run on its own decelaration a couple of meters, to save a bit on the brakes.

Usually, the RPM drop to almost 300-400 before "bouncing" back to near 600 idle. But last week, it dropped so low the engine stalled.

I think this could be dangerous if I was in a curve (since the steering is harder when the car is not on)... but I wasnt and managed to just start the car back while rolling and everything went good after that.

This is very intermitant, since it does not happen when Im in traffic or else...

anyways, you guys have any thoughts?

Your idle control may be off or not reading correctly.Check the faq section if theres a way to adjust it, or simply reset the ecu and see if that helps.

Low Idle

Hey I am having the same prob. I have replaced my coils and my MAF and it wasn't either of them. So are you guys thinking resetting the ecu will do it? If so that would be great. Sometimes I get nervous that it's going to stall.

if I reset my ECU (i guess by unplugging my battery for half an hour or so), it is supposed to change my idle???

Just turn your idle up a bit. Also check the tension on your throttle cable and make sure that is tight

How do you do that? Change the idle I mean. Also how do you clean your throttle body? I've looked and can't seem to find the "how to" on it.
