When starting my car on a cold morning, the auto choke raises the idling rpm to about 2000. It's normally 800 rpm or so.

As I brake, the car slows down (the brakes can overcome the engine) but on releasing the brake the engine is still wanting to rev high and the car lurches forward into the back of another car (not every morning).

I suggest that the auto choke should increase the revs only whilst in neutral or with the clutch depressed.

Don't know how cars with auto gearboxes behave as I drive a manual.

Move to a warmer climate. Problem doesn't exist for most of the world.

It's two years old and in Honda's current line up. Maybe the word 'choke' is carried over from the good old days, but the engine management raises the revs when it's cold.

Proper use of the clutch is to leave it engaged and disengage just before stopping. If you're free-wheeling, then you aren't in control of your car. I agree with this, but can't take credit for it.

Maybe by developing a cure myself I could earn enough money to //move to a warmer climate// and then //acquire a newer vehicle//

Sheesh.

Wasted space - you wasted space by posting your anno twice...

Happens sometimes. Your a victim of the halfbakery echo syndrome.

[energy guy] - I took the liberty of deleting the repeated anno.

[WastedSpace] - Wasn't getting lumpy whatsoever. Apologies if you interpreted it that way. What we need is a method of communicating emotions using icons. Mmmm.

To clarify. Braking - not stopping - releasing the brake. The engine pulls the car back to a speed equivalent to 2000 rpm, where I'd be expecting a speed equivalent to 800 rpm.

I mentioned the free wheeling thing to address your reference to proper use of the clutch. I could alleviate my problem by pressing the clutch while braking and using the clutch to 'feed in' the speed again, but this is frowned upon by the Institute of Advanced Motorists, of which I'm a member. Non-driven wheels are more susceptible to locking up.

I guessed that the only time the engine is in danger of stalling is when the wheels aren't pulling the engine round.

In all honesty, it doesn't happen for a long time, but crucially it happens at the junction at the end of my road. It's 6am, I'm tired. You get the picture...

You're wrong [El D J]. All cars idle higher when the 'choke' (call it what you will) is on, so when idling, the car goes faster than it would when the choke isn't on.

If you don't know what a choke is, then you live somewhere a sight warmer than me. This puts you in a poor position to comment on this idea.

Cruise control is deactivated when the clutch is pressed. What I'm saying is the Auto Choke does the opposite.

//Institute of Advanced Motorists// That means UK, and UK means it's not really particularly cold (unless you live at the top of Ben Nevis). Also an advanced motorist would know to feed the clutch in progressively to avoid sudden jerks. But that's beside the point.

From my hazy recollection of driving cars with manual chokes it was required both when idling and when in motion, until the engine warmed up sufficiently. Misuse would result in a rough engine note and lack of power. Don't the engine management systems in modern cars essentially act similarly?
