So last week I was on my way to the Jets game, and I was at this yield sign about to yield onto an interstate. Cars were flying by so I couldn't go. This is right outside NYC and there was a ton of cars behind me and I was holding everyone up.

All of a sudden a huge Cadillac FLEW UP ON MY RIGHT, trying to get around me, and I was like WTFFF so I FLOORED IT AND TOOK OFF FASTER THAN EVER BEFORE. I swear I've never done such a fast perfect launch with the Xfire EVER. It was perfect.

Then a few moments later I passed a bus and thats when my "Check Engine Light" came on. Damn was I pissed but it was running fine. I couldn't take it in for a week and a half because I had this state licensing class that they only run once a month! Plus it was running fine.

So this morning I got it in and they fixed it.. He said that "Cylinder 4 Misfired" and let me look into it a little more and see what happened, sometimes that happens. So eventually he said he found a TSB (Technical Service Bulletin) for my problem, and all he needed to do was flash and reprogram my ECU with the new codes.

So WHATEVER that means. It doesn't run like it used to AT ALL. Shifting even feels different. And only now the damn thing is running faster than ever before. I've got about 10k miles on her and now the transmission is broken in and silky smooth as well.

But like seriously, I have a few questions??

WTF is with the 4th Cylinder misfiring at all??

And WHY would I need a new ECU programming done at all..?

I remember one other guy on here saying something that the same thing was done to his.
