Other than a slight transmission fluid leak, our Acura TL has been powerful and dependable. Last week, I left the house and within a 1/2 mile, the check engine light came on. First steady, then blinking, then seady. Shortly thereafter, the TCS light came on (steady). Took it for the codes to be read and at first had codes P0301, P0302, P0304, P0305, P0306, P0300 and P1399.

Had a tune up performed, oil changed, air filter changed. The intake had some carbon build up and that was cleaned out.

Now it reads P0300, P0303, P0304, P0305, P0306 and P1399. Check Engine light returned stedy/blinking/steady/blinking, etc., and TCS light is on, too.

It was mentioned that it might be the control module. Any other ideas? Appreciate any ideas.

THANKS!

Hi carolinafour,

Thank you for the donation.

The codes are misfiring codes and diagnostics have to be carried out to determine the cuase.

During the tune-up, what were the items replaced?
