Hi All;

 

Just a question, someone might know.

My little 20 year old ECHO starts first kick every time.

Idles away, no problem.

I can take off and drive it, and as long as I don't stop for at least 1-2 klm, it never has an issue.

But I drive 50 meters to the corner of my street, stop, and then drive up the road...every day.

The car stalls when I hit the gas after stopping, nearly every time.

Only this once, once its warmed up or has driven 1-2 klm, never an issue.

It has also done this at work, where I drive about 50 meters to the front gate, stop and drive off....again, occasional stall.

The car is otherwise performing faultlessly, if a little gutless (but that's because I'm used to much bigger engines)

I drive 75-80 klm each way every day, at highway speeds, no problem.

and I can start it and drive any time after its warmed up without any stalling, its only when its cold that it has a problem.

I recently replaced the plugs, made no difference.

 

Any suggestions??????

Initially, I was going to suggest looking for vacuum leaks then I did a Google search to confirm those thoughts.

Just noticed that one URL mentions the crankshaft position sensor which I have recently replaced on the girlfriend's Yaris after it displayed a Check Engine Light.

An other URL is mentioning the coolant sensor.

After reading your post I checked all the vac hoses, all good.

But I did replace the MAF sensor, I had a spare in the shed.

This seems to have fixed the problem, hasn't done it since.

 

And on the matter of engine check lights.

I pulled the plug from the MAF sensor while the engine was running (the engine stopped, go figure?)

But the engine warning light came on.

The trick to turn it back off is simple, thought you might like to know.

Turn the engine on and off three times in succession....light out.

However, if it comes back on again, you got issues.

Cheers

just to close out this post.

Replacing the MAF sensor fixed the problem.

No more stalling and the car runs better.

who woulda thunk it?????

Was it a case of a faulty MAF sensor or possibly one in need of cleaning ? I rarely hear of instances where the MAF is actually faulty.

I've never tired, but I assume that if you unplug the MAF sensor, the engine should stall yes ?
