CEL after J37 IM/TB upgrade

please help!

I’ve heard of people having erratic idle with the j37 tb, but I can’t explain the misfire. Maybe I didn’t reinstall the fuel injectors correctly?

installed p2r runners, j37 im & tb, thermal gaskets, aem v2 cai.

now I have this:

Thoughts?

CEL turned off after driving about 50 miles or so. The P0108 was still in there when I hooked up my scan tool, but the dash light was not illuminated.

Did you try the TB relearn procedure?

is that the same thing as the idle relearn thing?

It's running fine now, but I plan to try the j37 IM & TB again soon.

So I tried swapping the motor and tps sensor from my stock tb to the j37 tb and I got a p0122 and a p2176.

Those of you who have done the j37 IM/TB mod - how did you make it work?

Fwiw, my j37 IM & TB came off of a 2010 mdx.

so far so good

put the TPS from a 4G 3.5 TL onto the j37 TB and that seems to have done the trick. briefly got a P0113 for the IAT sensor but it has not come back on since clearing it and driving 50 miles.
