hi, everybody: my car is 2002 ford taurus sel and miliage is 76,000 miles. When I am stoping and waitting for green lights at the crossing, the car will shake occationally. Recently it shakes more and if I turn on Air Conditionor, it will shake dramatically.
Now the check engine light is on and I bought a code reader it shows the problem are P0301 and P0316. It says I need to change spark plugs for p0301. for p0316 it says is problem about crank sensor.
Can you guys tell me what I should do? Thank you
and I asked the mechanic for changing the 6 spark plugs and the wire is totally about 300 dollars. Is it ok for this work?
