Ok so I just replaced my mass air flow sensor, and just replaced 3 spark plugs its a 97 cutlass supreme.. anyways the last 3 plugs are they hard to replace.

seems to ride smoother but check engine light is still flashing. I did get it checked out and I was told it could be my mass air flow (changed that today) and that my master cylinder 3 was misfiring (replaced the spark plug for 1-2-3 today) and they told me it could be 1 of 3 things, spark plug, wiring, or coil. Now if it was my coil wouldnt 3 and 6 be bad or no?

 

Take it to Auto Zone or Advance and they'll run their scanner on it for free. Then you'll know for sure.

You only changed 3 of the spark plugs????

just the ones I could get to right now. on monday I will change the rest.

 

One more thing...disconnect the battery for a few minutes. It'll reset the computer and might clear the error.
