Ok so after not really trusting what my wife was explaining about the problem with the car, I drove the car for about 20 miles, with street driving and interstate driving and it ran fine, with no isues.
A couple of days later we took the car out for dinner. Just driving down the street, a couple blocks, under normal accelleration, i could feel the car surging a little, and the tac bouncing a couple hundred rpm. Got on the interstate and accelerated to speed, about 65 mph cruising and when you accelerate a litle to around 2500 rpm the car would start surging and tac bouncing a couple hundred rpm. If you let off to under 2500 the ca would quit surging.
After dinner, just driving down the street at about 35-40, the car just died, but fired right back up. There was no engine light displayed.
Now my wife claims that even driving down the interstate, some times the car will just die, but will start right back up.
Yesterday She was driving and it and it died while moving, and the check engine light finnaly came on. When I checked it there were 4 codes in the system, P0171, PO327, P0336 and P0716. Now I am not sure if the crank position sensor code was allready in there, becouse there were no engine light on, when i changed the cps and I did not check for stored codes. The CPS is only a couple of weeks old. and what the car is doing now is not the same as before the CPS change. Any Ideas?.....
