Rough Idle At Start

Anyone else have rough idle at start. Just got car back from dealer for the second time, they have replaced injector 5 and 6. It still has a rough idle they say computer showed injector not firing right on over 200 occasions:(:(:(:( on the first time last last week. It feels like a cylinder is missing for about 20 seconds, rev the engine and it smooths out. Taking it back Monday with only 34000 miles and telling them to change plugs and start checking coil packs. They are not diagnosing very good or the whole injector rail system is bad!!

I've not experienced anything like this. Sucks, I take it this isn't the same thing as TSB 148?
Good point GrimReaper, there should be at least 1 entire thread around here somewhere (few years ago) that discusses this.

Also, our manual recommends that we use Chevron Techron fuel additive every 7k miles as part of standard maintenance.
Sounds like he got a dud. Oh well, some people can't/don't want to work out problems. I get it's inconvenient but I wonder how big the hit was on trading it in like that so soon (I'm assuming).
