You have 5 error codes for misfires. Have you discussed this issue with your tuner?

Are you using an aftermarket clutch and flywheel?

spunker yea i have talked to the tuner. we did erase the code and it is drive fine. after 3to4 min cruising it show up fuel status error then sputter (misfire). injectors show 0ms at 3k rpm. i have no check e light when it sputter but would u show me how to look up check engine code in flashpro. and yes i have competition stage 4 clutch kit. it happen while switch to open and back to close loop within 3krpm. thank u

Have you tried disabling the misfire detection? This is usually triggered by an aftermarket clutch and flywheel.

spunker. in the misc the tuner uncheck everything except misfire detection. i will talk to him about it. also tuner wants to replace upstream o2. we will do that and test drive again then i will let u know. thank u so much
