IV had this surging problem for a while now but it gotten worse. Now i can feel it surging while idling no matter what gear its in and then in 15-30 seconds it just stalls. It idles around 500-750 RPM surges and dies.
I can hear it not squeal but moan when idling, when i hit the gas the moaning goes away.
Iv cleaned the Idle Air Control Valve , EGR Valve, Throttle Body, and the mass air flow sensor, still surges and dies.
i bought a new PCV Valve and a new PCV valve elbow, since my old one cracked and swollen in. ran good for a while then back to surging problems
I cant afford bringing it to a dealership to take a look at it since im on College but i would greatly appreciate anyones help

Thanks

 

Have you checked your plugs and wires, my escort was surging and its what I did and it went away. Hope this helps

 

....have you checked for vacuum leaks?..
