car stalls

[motroman]

It's happened twice in the last two weeks. First someone cuts me off driving in the city. I hit the brakes hard,.the car stalls. Just restart and go.

Next, yesterday. My wife exits the freeway a little too fast. The offramp is one of those 25 m.p.h. jobs that has a sharp turn to the right. She hits the brakes hard from 65 m.p.h.(instead of gradually slowing down..just don't go there because we already had that discussion!),..and the car stalls while going up the offramp. Pull over quickly, restart, and we're on our way.

So, what's causing this problem?

I had this same problem when I first bought my car. The fix was to adjust the throttle stop screw (a.k.a. min. air screw) to get the IAC setting correct.

Here's how to do it without a scan tool...

Here's how to do it with a scan tool (the prefered method)...

The trick is repeatedly tweaking the throttle blade min. air screw and the TPS sensor until you get it right. A "perfect" setting is having the IAC at about 20-25 counts in Park at idle (engine fully warmed-up), while having the TPS sensor reading about 0.42 volts.

Good Luck,

Thanks,...I'll work on this next week.

Check that your battery cable is not hitting something hot when you hit the brakes.
