I think my FPR may have went bad. No matter how i adjust it the thing doesnt richen up or lean out linearly.

The only time that my car sees the right AFR is at full throttle. When cruising its dumping fuel. (richer than my wideband can read) and it also goes super lean at times. At idle it starts at around 15:1 and with a few seconds richens to an unreadable amount.

Does this sound like its screwed up to you? I think the diaphrams get screwed up.
Its a B&M command flo

 

i could never get my b+m to work right, threw it away.

 

Mine has been great for atleast 3 prolly 4 years. I just think it might have finally went

 

I think I'm having the same issue... I have a B&M too. It will work fine, but if I'm doing a full throttle run, it will lean out around 7k every single time, somtimes really bad, and othertimes its okay. This is with two different ECU's.

I'm ordering a new FPR to see if it solves the problem.

 

u get another b&m or something different? Mine acts funny too like not always running rich sometimes its fine, sometimes lean and makes it cut out, and sometimes dumping fuel. all within the same rpms and conditions

Wow. Mine does the same damn thing. No, I'm not getting another B&M. I'll probably get a SARD or an AEM or something.

 

Up?

Anyone have this problem? I ordered an AEM, becaue this B&M piece is garbage..
