  2. No throttle response

    General E46 Forum
    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...

    General E46 Forum
    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...
  4. Light throttle bucking

    ///M3 Forum
    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...

    General E46 Forum
    Any clue fanatics? 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...

    So, I was driving back to Arizona on Monday after Thanksgiving break and passed through Flagstaff. It was below 30 degrees and snowing hard.

  11. How should throttle body operate on N42 engine?

    General E46 Forum
    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...

  13. Throttle Sensor - EML - P0221

    General E46 Forum
    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...

  15. Throttle response delay after engine warms up

    General E46 Forum
    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...

No real mods aside from the golf-tee, a K&N filter, a rebuilt DISA valve, and a Dyanvin head unit as...

    General E46 Forum
    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...
  18. Sprint Booster DIY?

    General E46 Forum
    Soooo I just read this thread: 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?
