So, I blew my brake booster check valve for my 01 325i (auto), and had to pull the intake to replace it, I already knew the process for getting it out and all, so everything goes fine. Then after everything is back together and connected, I try to start it, and it doesn't start. So I remove all...

I have a 2002 330i 5 speed. I have an issue where I can rev the pedal in neutral and accelerate in 1st gear UNTIL I take my foot off the gas. There is then no response from the pedal once it has been let up. I then have to reset the battery and it works again for the first time I press the...

When driving at light throttle my M3 will buck as if I am on and off the throttle rapidly. Been chasing this for a while. Have replaced both TPS and swapped in a different throttle pedal to no effect. Problem typically happens under 45mph. It never happens, for instance, with cruise control...

Let me begin from the start. I bought a bmw 320d couple years back, it was pulling like rocket. Fast forward coupe of mounths, i was touring toughout my country and at some point i wanted to se how fast i can go(im smart i know), so i reached 205kmh and drove it for maybie 5 mins at that speed...

Any clue fanatics? https://www.youtube.com/watch?v=ElBR-Wlm3LQ I'm going to poke around the hoses that connect to the evap and wherever else, new code for me. Driving on the highway with the throttle response like this is very weird... kinda like an automatic cruise control, except more...

I am going to be as simple as possible, here are the codes, car don't pass over 2000 RPM and RPM fluctuates after I clear the code they appear later, BTW I don't have the plastic shields that are underneath the engine. OBD Fusion Codes: P0221 Throttle/Pedal Position Sensor/Switch "B"Circuit...

So, I was driving back to Arizona on Monday after Thanksgiving break and passed through Flagstaff. It was below 30 degrees and snowing hard. I was moving from a stop and trying to catch up to traffic speed (had to pull over to the side of the freeway for a few minutes) when I lost traction for a...

I have a problem on my 318 that I think is related with valvetronic operation. Car stalls sometimes when warming up. power and MPG are pretty bad. Actually I'm not sure valvetronic works at all, because I was driving few days with disconnected sensor and didn't feel difference. Today I...

My 2000 323i Sport Wagon is making a couple very strange whistle sounds. Here are the conditions for the first one: 1) It only happens in Drive - not Park or Neutral 2) It is not affected by the AC being on or off 3) It is only audible at low RPM (1200-2500) 4) It does not occur at idle 5) It...

So I've been having the christmas tree light up (the one where the ornaments are: DSC, ABS, BRAKE, EML) since I bought the car, but it's never been often enough for me to do anything about it. The lights would come on, sometimes with a P0221 error code, I would restart the car and keep driving...

Hi all, First time on this forum, since I just bought my M3 this week. Unfortunately, I need help diagnosing a problem that the prepurchase inspection missed. :censor: The car is a 2006 M3 6-speed manual with 59K miles. On the drive home from buying the car (all highway) I took it easy...

Good Morning Bimmers ~ I have a 2002 325CI and recently there has been a slight delay in throttle response (I push down the gas pedal and a second elapses before the engine revs up). I've read about a way to "reset" the throttle response, which apparently automatically adjusts, and can be...

Hello there, I tried searching for this problem via Fanatics and Google and came up short. I have a 330XI with the 5-speed manual trans @ 130K miles - I've had the car for just over two years. No real mods aside from the golf-tee, a K&N filter, a rebuilt DISA valve, and a Dyanvin head unit as...

Hey guys, I've had a 2003 325i for about 3 years now and have had no problems until recently. About a month ago, the EML and SES light will come on while I'm driving. It comes on for about 2 or 3 seconds and then it will turn off. While its on it seems like the engine is stalling or in limp...

Soooo I just read this thread: http://www.bimmerfest.com/forums/showthread.php?t=378725. If a Sprint Booster is such a simple device, would it be possible to make a simple version of one for fractions of the price? :hmm: Maybe you could even make one that has adjustable amounts of throttle change?

I want to get rid of the throttle lag on my 330ci and would be happy with some small hp gains. Should i get the shark injecotor or the sprint booster which is better?

Hello everyone, I'm new to this forum and I hope you can help me out. I'm driving E46 320i touring year 2002, M54 and last time when I started my engine it started acting wierd. Lights engine service soon, eml, dsc came on. It's same as on this video...

I recently purchased a used 02 325ci.. Since then it seems it's spent more time being driven by a mechanic than myself.. I have this problem.. Well, my car does.. Driving to work on a steady/light THROTTLE also UNDER LOAD at around 1500-2000 rpm I'm experiencing a vibration/shudder/noise and its...

I bought this car with 130K on it from the original owner. 2002 325 XI with the electronic throttle (no cable). There is one annoying problem that I can not get resolved. The problem: When I give it 100% throttle then suddenly let off the car continues to go full power for about a half...
