Check engine lights on and hesitates on all rpm range, I used my cheap scanner and got P0300 and P0301, which said #! cylinder misfire and random cylinder misfire. What is the next easiest step? I have a small basic engine knowledge but by far not an expert, What i'm saying is you could easily point me to the right directions. One more info, This problem comes and go and most cases starts acting up after engine warmed up.

For misfires, at that mileage, start basic and do a tune up with OEM parts.Clear the code and see if it comes back. If it does with the same code, you may need to have a shop with a real scanner plug in and see what they can find. Also check for vacuum leaks
