Engine Performance problem
2000 Ford Taurus 6 cyl Two Wheel Drive Automatic 75000 miles
my car started surgeing one day while driving, I installed a new egr sesor, spark plugs, fuel filter. Ran good for a week than check engine started flashing, drove fine but surging started again later. Than check engine came on and read to lean bank 1 and 2 so checked hoses was a leak in the pcv elbow. Replaced the elbow and pcv. After that ran really good better than ever but when I turned my ac on the car died also happens when I brake to stop and when I put the car in gear the rpms go up and down like its about to die. I replaced the idle air control and still happens. Alternator reads only putting out 36 volts I think the people said it is putting out weak signals but dont know if that is the problem what do you think?
