This is probably a crazy idea - but - maybe reset the ecu?

Drove it around for a bit, and she did definitely saw gray smoke once, and maybe a second time, out of 15-20 attempts.

I guess I'll wait until the Leprechaun run when hopefully Greg will be behind me to watch....

Keeping my fingers crossed!
Nice, was likely the unburnt gases as mentioned by Joey. Boy knows his stuff.

one check you can do since you're already done 4,835, a wet compression test.

new injectors, new plugs, compression good, oil consumption not bad, gas mileage not bad...i say carry on and let it be.

You need the stock cat back on the car then. Otherwise i tend to agree, it is what it is. Nothing amiss.

Hope to get the car out in a few weeks, and hit some backroads to see if the Supra pcv valve has corrected the issue.

If not, will be trying a stock cat.... just need to find a S2000 parked on the street, or in a garage so I can borrow their cat!
