Hey- I have a 09 ford mustang GT 4.6 v8. I have LT headers, 47lb injectors, hot rod cams, CAI (JLT), 62mm bbk TB. I’m also tuned on e85 and that’s what I’m currently running. I’ve checked for air leaks in intake system and exhaust system. No issues there. I’ve also swapped injectors with brand new ones. I get a p2198 code while idling. I can’t seem to find out why. I’ve talked to my tuner and he said it’s either an exhaust leak or leaking injector. But I’ve tested for both. Both passes even with new injectors. I’ve watched Live Data multiple times and took vids and screenshots of how things are doing. I’ll upload some screenshots of data. I’ve taken vids of how things was going on live data but I can’t upload vids. Someone please help.
Thanks
Ps: I’ve added the pics in order from idle to 3k open throttle. If this doesn’t show enough I can try to upload more. But my fuel trims on bank 2 are way off. It’s taking away a good amount of fuel on that side.
Ps: pic starting from 3-8 are recent pics I just took while letting it idle for a good 10-15 mins. Everything started to look normal the longer the vehicle idled.
