Sor codes if engine light blinks. An d if was rebuilt a couple of weeks ago from a blown engine all the oil and other stuff may not be quite out of the system yet. Or take it back to where it was done and complain.

Thank you. We took it back to the guy that rebuilt the engine. He can not find anything wrong. Says oxygen sensor is bad and the motor mounts are bad. But he drove it and says it's good. But will look at it tomorrow and see if all is okay and I thank you for your response.

Good evening,

The flashing check engine light indicates a misfire. I attached a guide for you below of possible causes.

I would check the fuel pressure to be sure the fuel pump is working correctly.

400 kpa ±34 kpa (58 psi ± 5 psi)

There are 3 types of smoke. Each color indicates something different. I attached all 3 below for you to view.
