Looks like compression test is next on the list. Was also thinking of doing walnut blast as I don’t think it’s been done.

What adapter do you use for compression tester?
I never hooked it up to INPA. I did use MHD to run some logs at idle. The fuel trims were all great, AFR's were good, VANOS numbers all good.....as far as the data goes, everything was fine. No codes...nothing.

I just felt that odd idle that felt slightly rough...that it.

My compressor tester kit came with several difference spark plug thread adapters...I just picked the one that fit
