Took mine out again on lunch and while it didnt run perfectly like on the way to work with the TCS off, it still drove much better. (had a few misses here and there) It seemed to get better once it was warm tho.

If your gets better as the car warms up it would seem you have a mechanical problem mine is intermittent and does not matter if the car warmed up or stone cold

I let my car warm up 3-5 minutes every time before I drive. This is because I have dual valve springs. I have driven the car like once or twice without letting it warm up and it missed all over the place, just like you are mentioning. If you have dual valve springs then you absolutely NEED to let your car warm up. Without doing this, you risk valvetrain failure.

Only engine mods i know of are HPE S cam and HPE tuned, Kooks long tubes, meziere electric water pump.
Its also not setting off any mis fire codes, but is setting off codes p0134, p1133 and p1153
I suppose i could take the valve covers off this weekend and see whats under there.
In the mean time, ill be starting it up and letting it run till it is at op temp.

Well guys ive taken the vehicle to two mechanics no one could tell me anything for sure well i drove the car to miami from nc and well when i got there my low oil came on. I decided to do an oil change. The ses light flashed from time to time but there was no random missfire code that came up when i got to florida. I drove the vehicle all the way home to nc and the low oil light came on again. I noticed a leak on the driver side under carriage but couldnt pinpoint it.
Now i did record a video since a mechanic told me it could be valve seal causing the missfire but there is no smoke on a cold start at all. Car runs fine for a while but when warm.starts to missfire i got the flashing ses light a few times on my 1000 mile drive but then it jist fix itself.

A buddy at work advised it could be a faulty coil pack and as for the oil leak he said it could be the oil pressure switch i can deal with the oil leak and fix that later but as far as the coil pack is there any easy way to check like disconnecting them while its running?? This is the closest ive gotten to an answer when i pull the codes up in nc i got a bank 2 system too lean and of course insufficient switching bank 2 any more idea guys. I have no ne around here that has a clue but im trying my best to diagnose
