Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 1 year ago.

The misfires you are feeling can be a variety of things from coils to fuel injectors to low compression from a jumped timing chain.

You will need to do some diagnostics on these items prior to replacing anything because it can get expensive.

Thanks, Ron

I checked all those possibilities, no problem with the coils , no low compression , if the chain jumped I would have a mess, it runs smooth then idles rough , then blinking light come on ,put it in drive light goes out

Well then that would have to be a defective computer if it's not throwing any codes and the CRANK sensor is good. The flashing light means a misfire as you know and codes should be set. You can also attach your scan tool to read all the data being outputted.

Thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.
