Loss of power??

Dvdman · 09-27-2010, 09:02 AM

I have a 335xi 08 and was driving to the train station this morning when i got a half filled engine pop up. I loss major power and pulled over. I restarted it and same thing happened again a mile down. I almost got hit crossing a road as i lost power while I was crossing. I needed to get to work today and couldnt miss my train so I kept going. I pulled over again and restarted my engine. The engine light did not pop up this time. WTF? My car was in the garage all weekend. I didnt use it at all. I woke up this morning and warmed it up for that reason. No long crank. I just had my HPFP replaced 1 month ago. Is this the HPFP again or something else? The SES didnt come on. I read usually HPFP are accompanied by a SES light. Also, I have a JB3 and DCI in it. Is it possible these are the cause? They are hooked up right. I mean its a 08 with 14k miles on it. How could a barely used BMW have these issues? I have 2 kids and I am worried if something like this happens with them in the car an accident could happen. I have read on the forums about the loss of power and such but I just had the HPFP replaced so Im thinking its something else. Any opinions?

I am getting nowhere near the HP\torque that i got when I installed the JB3.

I picked up my car at the airport yesterday and it felt like it would barely move... in the parking lot... Not sure whats going on with it. When I go into open throttle, it downshifts, but nothing impressive. Feels like a little less pick up that stock.

I have had the JB3 for maybe 5 months now and wondering if something else is happening internally. This has been happening for about a month now, and yeterday it through a F033 code at around 5200 rpm. Could this be a conpession issue considering it just decided to throw a code (which might not be related)?

To add>
I did run it out of gas.
