Question
QUESTION: Replaced plugs and plug coils and truck is still running rough

ANSWER: Hi John -

Can you tell me if your check engine light is on?
Have you checked for a vacuum leak?

QUESTION: Calvin, engine light flashes. 07 Nissan Frontier, 4.0L

Answer
Hi John -

OK. If the above vacuum leak test is negative, then you will need to go and get the engine code (OBD) diagnosed and downloaded. If you have Autozone in the area, they can do it, or just about any auto repair shop.

Once you give me the number, we can go to the next step -

Hope this helps -
