Why does car miss and hesitate while accelerating? Check engine light is on.

(2000 Volvo S40)

It seems to happen more under harder acceleration. Check engine flashes when it happens. I replaced fuel filter. Advance autos scan would not read code.

I've seen spark plugs that are non-Volvo, or even Volvo plugs with 20,000+ miles cause misfires. You may also have a bad coil too. Try new Volvo plugs and see if that helps. Try not to drive when the light is flashing, this will damage your catalytic converter $$$.

Need to get the code. Go to different places like Autozone or Oreilly auto,Checker/Kragen auto parts for free code scan.
