I know it is TSB# 120299 MAY 99 Motorsport Engine Runs Rough on Cold Start .

But I wanted to read it first hand completely.

Thanks for any assistance!

I still have the cold rough start, and all of my searching hasn't produced any info that I can thwart my dealer's claims that '...it is normal with the M engines....'

Anything anyone have here?

And yes, it really does make a difference on cold start even in a moderate climate like LA. Heal/toe downshifts are easier, too.

But this TSB is for S54 engines. This isn't the one for S52's.

Thanks guys. And yeah, it is for the S54. Grrr. Too bad, because this is exactly what I experience.
