AFR problem?
Hey guys well need some ideas, I have a 2009 ss with rpd, mods are typhoon k&n intake and high flow dp from turboxs and hp tuned. Well problem is when im driving when the fuel pressure is around 750~ and going around 75mph the car feels like its diving its not to big dive so im super worried but its annoying, if you pay attention you can feel it. Also I have noticed that the afr when it does the dive it jumps from 13~ to 16~. I have an idea of what it could be maybe a dirty TB, injectors or maybe a going bad BPV?

Well my tuner said the afr is good, so I was trying to rule it out. Should I try to seafoam the car? It did something different today butwith all my work stuff I kinda forgot what It did lol

I had this issue with trifecta tune, it ended up being the trifecta tune sucked. but another reason it could be doing this is the evap solenoid may not be working properly. totally disconnect the evap solenoid power and the vapor hose from the solenoid and go driving and see if it still does it.

Alright thanks ill check it out. Also on the k&n does it matter the way you install the filter I had it the fat side up I guess if you can call it that way (meaning that one side is thicker than the other one) I did a 180 turn on it and I didnt notice it on my way home last night and on the way to work right now, but then again was falling asleep while driving today so wasn't paying to much attention lol

Hey guys well today I got a new problem when it started my car it rev itself after a few second it warmed up and was running ok. Once I started to drive I could hear a backfire on the back of my exhaust when going from 1st to 2nd( in one of the recording you can hear me say it), then after that I noticed my afr was going crazy from 10 to 14 then all the way to 18 and thats the max reading on the rpd and the car kept jerking back and forward. I will be posting some recordings I was able to get the sound isnt the best but you can hear the blow off and thats when my afr is doing what I explained on top. Also it seems to start messing up when I hear a sound the best way I can explain it would be when you go over standing water with the car it kinda sounds like it but I wanst able to get a good sound off it also Ive had code p2176 that is minimal throttle position not learned idk if the code could give such symptoms as I had the code for maybe a month and its the first time it gives me problems like that. Any help will be greatly appreciated
