OK, I am editing this post, this may or may not be CTSC related so if you are looking for specific CTSC issues, you may want to stop reading now.
--------------
So before I bought my NSX, I had 3 cars I kept stock. Why? because before those I had a Supra highly modified, and always had some little bug, something that would go wrong. Well, after a lot of research, I thought to myself a CTSC is as reliable as they come, and I added that to my NSX. I love the power, but now I am really wondering if I should have just kept it stock. I have this PITA misfiring issue that almost cost me a day at the track in NY last time (it did, but it rained so I just went home). Car sometimes just dies with both feet in. Drive down the highway, get to a toll, and watch the idle just drop and die. At the track finally CEL comes on, and I have like 7 codes, "random misfire" and "misfire cylinder 1"... "misfire cylinder 2"... "misfire cylinder 3" and all the way to 6. Took the car to my mechanic he runs all sorts of diagnostics, can't find anything but not quite 100% behavior on the 02 sensors. OK... I but two 02 sensors to the tune of $400, get under my car myself all day today, replace them, clear the codes, drive away, same shit. Car runs perfect for first half hour. I go to the grocery store, buy a few items, get back in the car. As I pull away, the car has no power... sputters... I get into higher RPM's and its a bit better, then just kinda goes away on its own. Cruising at 40... "pop".... runs fine.... "pop".... runs fine... "pop"...
I am Sooooooooooooooooooooo frustrated, I have a track day coming in a week, and still have this issue. I just held off buying a GTR because I thought my CTSC NSX was more fun. But what I didn't think of, is that there is no such thing as a CTSC NSX. There is the NSX, and then there is an aftermarket item you add to it, called a CTSC.
This misfire comes, goes. Comes, goes. I am at a loss. It feels more ignition to me than fuel, I just don't know what this could be. Would a loose wire in the comptech harness feeding the ECU do this? I'm going back to the mechanic, spend another $1000 in diagnostic time, see if I can figure this out. This SUX.
