K24 swap fg2 HELP

Post by Smears99 »

I recently bought a 2006 fg2 with a k24 swap from an 06 tsx.
What I’ve been told by the previous owner.
Completely stock k24
Kept the intake manifold, exhaust and trans from the k20z
No ecu re-flash or anything like that.

The fact that it was running well when I bought it makes me think the ecu had to have been messed with somewhat.

It ran well for about 2 weeks and all of a sudden horrible misfire on all four cylinders and all misfire codes along with it.
Was able to baby it all the way home. I will not even attempt to drive it the way it is.
Pulled the plugs and there showing very lean.
Replaced them to no avail.
Assuming I need to get hondata reflash or kpro.
Have no idea where to begin. So any suggestions are greatly appreciated.

You would need the FlashPro to be able to custom tune this: https://www.hondata.com/products/flashp ... s?filter=7
