Crankcase (pcv) problems of the 2001 Ford Focus

I have a 2001 Ford Focus lx with 199,871 miles on it and its my first Ford car. I have owned many of Ford trucks in my life and always fixed problems with them myself. But with my Focus, every time in the past 4 years when I turn a corner roughly around 15 mph or over, it cuts out and the car bogs out and jumps like the engine is going to jump out then I get a bad smell almost like sulfur coming from the car. All fluid levels are good with a full gas tank. This happens whether the car is hot or cold. Usually I can just punch the gas pedal to the floor and it will eventually gain rpm's again and go with no problems until I turn sharp again. I have recently replaced spark plugs and cables, alternator, transmission and clutch plate, fuel pump and various pcv valves and hoses. Had the fuel pressure tested and it was fine. This problem has been consistent like this for the past 4 years with no other problems. I have always been a Ford guru but this car is making me think twice. I have 2 small children that go with me almost everywhere with me and just today as I turned a corner getting on the highway ramp, it bogged out worse then ever with many angry drivers on my tail. I thought I was going to crash the car into the guard rail. I hit the pedal to the floor like I usually do and it started going again, but in fifth gear it kept jumping and cutting out. I turned off the side of the road to turn the car off then back on and it ran fine all the way home. I have read many forums with the same issues on my make and model and tried many solutions with no luck. With your expertise, do you have any ideas why this is happening. I see this problem allot with Focus's but never any working solutions.

The contact owns a 2001 Ford Focus. While driving approximately 35 mph on normal road conditions, the engine began to idle excessively high. On a separate occasion, the vehicle stalled without warning and lost power steering. The driver experienced extreme difficulty steering the vehicle and had to use excessive force to turn the steering wheel. The vehicle was able to resume normal operation. The failures occurred intermittently. The vehicle was taken to an authorized dealer and they wanted to charge the contact for a diagnostic; however, the contact refused due to the cost. The technician refused to repair the vehicle unless the aftermarket parts were replaced by the manufacturer. The parts consisted of the pcv valve and fuel filter. The vehicle has not been repaired. The manufacturer conducted a campaign (03v-482) to address the stalling in the vehicles. The contact experienced the identical failures mentioned in the campaign, but the VIN was excluded. The failure mileage was 118,000 and current mileage was 119,000.

Consumer states while pulling off from a yield or stop vehicle will lose power. Vehicle chekced by dealer who could not determine cause of problem. Consumer stated that this problem seems to happen when slowing down or accelerating from a stop or yield, the dealern replaced mass air flow sensor and pcv valve but this did not correct the problem.
