2011 Honda Odyssey, 150k miles (not muzzled)
timing belt/WP done at 110k miles.
Last weekend the van popped a bunch of misfire codes. P0300,P0301, P0302, P0303. (Permanent)
I replace spark plugs, ignition coils, fuel injectors, drain the gas tank, cleaned fuel pump filter, added fresh 91 gas. But on first drive with it new codes popped.
P0108- MAP sensor circuit high voltage
P0123- TP (A) voltage high
P0223- TP (B) voltage high
it once again idles rough/ shaking and has no pep on acceleration.
anyone have any idea or advice because at this point I’m just throwing parts at it but nothing is working.

 

Check for restricted exhaust.

 

any recommendations/ tips how to check that?

 

I like to use a vacuum gauge. You can take the pre-cat O2 sensor out and see if it runs better.
