I got a walbro for my car and installed it. went smoothly. i took the car for a drive and made 3 pulls in about a 5 mile period. everything was fine to that point. then coming home just cruising I noticed that my afr was around 12 when its suppose to be at 14.7. got to a gas station and the car almost died because it kept getting too lean. i would have to give it gas to keep the car running. this walbro is the first thing i have done to my fuel system.. i have heard they are loud and make a whining sound when on. mine is super quiet with no sound. could it be something else??

rich (12:1) when cruising. but it would go way lean (17:1) and go between that. thats when i was cruising at 35mph... no load with even throttle pressure. but when i would idle it would go up and up and up till like 21 afr. thats the limit of my wideband. around 18 and up the car would just about die... could it be a fuel pressure regulator?? and can those just go bad all of a sudden??
