Acura MDX with all Cylinders Misfiring

Topic starter

Hello Scotty, My 2005 Acura Mdx that is got 3 months ago with 156K Miles, it has misfires on all 6 cylinders. Still runs and drive good but it has a rough cold start and the mpg decreased from 17.0 to 13.4 MPG. I researched that this car needs a engine exhaust valve adjustment on each cylinder, every 130K miles. Any Advice on what is needed to be done?

Does your engine stall?

all cylinders misfire 😨

If it still starts and runs "good", 
 I say clean the throttle body with CRC cleaner and see how things change. You’d be surprised, this just may cure the problem significantly, 
 and than we can talk about valve adjustment.

There is Scotty’s vid on uTube that will show you how to clean a throttle body, btw. Just search for it.

F.S.
