Car stalls while driving & idles rough

I recently rebuild the engine. Car stalls while driving but always start back up immediately. I have replaced the camshaft sensor and the crank shaft sensor. After review several posting, the MAS air flow sensor maybe the problem. Can anyone tell me how should I disconnect to test. ie: disconnect while car is running or while car is shut off?


Any suggestions would be helpful.

Also check the EGR valve

The cam sensor has an interuptor on the cam gear, take off the cam sensor and see if you can see the interuptor, you can twist the balancer until you see it. Using two people it the best advice i can give.
