A bad cam shaft sensor will cause these symptoms as well as a bad
crank sensor. Since it's not throwing any codes for these items,
maybe clean your MAF with Mass Air Flow cleaner which you can
purchase at he auto store. If you have a 4 cyl. then your car doesn't
have a MAF. If you own a 6 cyl. then it does. Try changing out your
Engine Coolant Temp sensor also. If bad, that will screw up the fuel
mixture that the computer sends to the injectors. Pull a couple of your
spark plugs and see if they are black. If so, this is a sign that you are
having a too rich fuel mixture. If plugs are fouled, that is a sign that
your ECT (Engine Coolant Temp) sensor may be bad or your MAP
sensor. (Manifold Absolute Pressure) sensor.
