Optra Stalling

[kroz123]

Hi Guys, I recently been having problems with my car with stalling.

When it stalls it stalls when the car is in D.

And today it did it when I came to work and put it in R and it stalled but it starts right up.

I've changed numerous of things like the TPS and idle regulator valve also the fuel filter cuz the fuel sucks here.

And still nothing it still does it time to time.

I'am leaning toward a vacuum leak but I don't know.

Can you guys please help.

thanx

A few questions?

Do you get any Check Engine light codes?
Have you checked the basics spark plug/wires?
Check EGR Valve and gasket and wiring?
Check your o2 sensor?
last thing i can think of is fuel pressure regulator?

It sounds like there is a misfire due too too much fuel/too much EGR flow/not enough spark/too much air causing excess fuel..

good luck.
