Ok hopefully someone can figure this out.

When I'm at a stop (red light usually) the RPM and oil gauge rev up and down together, and makes the engine rev, sometimes so much that it makes the car go forward some when i have my foot on the brake! Sooner or later if I don't move it stalls out. When I do press to accelerate it loses power and theres a delay to get power to get moving.....

I have had the oxygen sensor replaced twice and that worked both times for 6 months, then it came back again!

This time I had the spark plugs changed and the wires (I did these myself, I assume I did them right) this had no effect on the van.....

I've tried STP Carb cleaner and Gumout stuff that you put in the gas tank, some seemed to work a little and some didn't work at all....
The van doesn't always do this as stops, but 90% of the time. I put it in neutral or park when it stalls out and it starts up just fine. Rarely it stalls out when I'm on the freeway or taking a big turn.......

Can anyone help me out here, its driving me crazy and I don't want to put an oxygen sensor in every 6 months!!!

Thanks
