Engine dies at stop sign
 
What can it be? So weird, it happened twice today, w/o any sign. Last she did this was back in 2011, when the Camshaft Position Sensor went wrong. Since I replaced the sensor the problem was gone, never came back.

It only happens at very low speed, i.e. come to a stop-sign, or a stop light. Usually it comes after a sharp steering (or during steering), which is very dangerous. Please advice, guys! Need your inputs! Fuel Pump aging?

BTW, no check engine light.

Thanks!

Sounds like another CPS going bad.

Since there is no CEL, I would suspect fuel pump.
When CPS goes bad, it throws CEL.

When I had that on symptom on 2 different cars, it was the MAF. No CEL as well.

Have you scanned for codes yet?

How does the engine sound? Maybe a large vacuum leak at intake gaskets and low rpm's are not enough fuel supply?
MAF's could be culprit too for sure.

Thanks for all the inputs, guys!

I did pull the code, NONE. odd.............

MAF? I'll take it out and clean it again, but not sure if this is the culprit, cuz the RPM and the engines sounds all fine.

If the fuel pump on its way, should there be a code?

Today is fine again, but I'm driving like a scared dog......:confused:

There is no code for fuel pump since it's not emission nor drivetrain issue.
