Im lost on this one. I am getting random misfires across all cylinders. I have done everything except for icm and fuel pump on this car. It seems to misfire worse when i first start it and less as it warms up. There is no check engine light and i only know its misfire due to scanning. At wot when trying to shift different gears it does it so bad at 100% load to the point the car jerks and wont shift until i let off the throttle. This started and seems to be getting worse ever since i tuned the car and disabled torque management completely. This brings me to believe fuel pump. My fuel trims are all within -3 and sometimes but rarely hit -5. Vacuum is good sitting at 20-23 idle. Ive seafoamed all cylinders multiple times. Fuel filter was changed about 6k-7k ago.
Injectors were taken off and cleaned and sprayed nicely. I did do the lim gasket and did torque the bolts correctly however i didnt think to put thread sealant on the bolts and dont really think that would cause issues after only 4k miles and my oil is perfect. It does seem to me there might be a slight leak that i cant pinpoint in my headers but can hear(possibly in my flex). Anyone have any ideas? This is driving me crazy i want to take this thing to the track the get some numbers befor winter hits.
