Is a code set?
What does that mean?
Check engine light on?
Yes and its flashing
Go to an Auto Zone have codes pulled then post
Codes p0301, p0303 and p0305 which is a misfire in cylinders 1,3 and 5, and they said something bout the emissions.
Was the same engine miss there before heads r&r? Has fuel injectors been checked on those cylinders? is miss at idle and under acceleration? Have vaccum leaks been checked ?
It was not missing before. Could it be something electrical?
The cylindes that are effected indicate an intake leak. Check injector connections if good . Consider pulling top intake and give close look at gasket seal.
