I have a problem when im driving down the highway at a steady pace, light throttle between 3-4000 rpm randomly my car will bog. It feels like the fuel is compleatly shut off.no matter how much throttle i give it it slows down. if i get off the throttle then slam it back to the floor it will snap out of it and stop the boging. I have switched out my ecu (p30) for a (p28) and same problem. I have a code 23 "knock" i don't think has to do with my problem b/c the p28 has no codes when i put it in. I also have a code 43 "Fuel supply system". I have tested everything i could think of but im up in arms over this one. any help would be rad.

 

bump cuz i have the same problem

 

it has something to do with your o2 sensor...reckeck your wires make sure you havent cross plugged any sensors...make sure you have a fresh working o2 sensor..if not change it...

 

ok cool cuz i'm changin it tomm anyways. i'll post with the results.

 

got the o2 sensor in and i am happy to report that the bog has disappeared. so has the hesitation that sometimes occured when i downshifted.

 

 

Thanks for the follow up... most never return to do that

 

well the way i look at it if i say i'm gonna do somethin , i'm gonna do it. i even want to apologize for it taking so long for the results.

 

same problem here, sometimes it feels like i have msd around 3.000, but i took it off
