  1. Hi Loren Thanks for the reply. I consistently get these codes even after I had my local shop replace my complete throttle body. P1506: Porsche fault code 413 - Throttle adjuster P0121: Porsche fault code 117 - Throttle valva Signal implausible P1122: Porsche fault code 431 - Throttle position sensor Signal implausible P0507: Porsche fault code 32 - Idle air control system exceeds limit value P1121: Porsche fault code 430 - Throttle position sensor Signal implausible On my last fault code check it also showed: P1504: Porsche fault code 410 - DVE fault: necessary intake air position Signal implausible When I clear the fault codes, these 3 pop up immediately: P0121: Porsche fault code 117 - Throttle valve Signal implausible P1122: Porsche fault code 431 - Throttle position sensor Signal implausible P1121: Porsche fault code 430 - Throttle position sensor Signal implausible When I accelerate to 4000 rpm (in any gear, tiptronic regardless if I shift manually or not) the throttle will cut out but the engine will still be running. I then put the car in neutral and start the car again and the throttle comes back. If I don't clear the codes the car's idle will eventually become erratic and fluctuate up to 2k and then back down to 800. If I clear the fault codes the idle goes back to normal. In my research I found someone with a similar throttle cut out problem and he said it was a MAF ground problem. I've checked the connection at the MAF and at the DME and it seems ok. I've opened the DME to see if there's anything out of the ordinary and all the components look ok as well. Any advice you could give would be totally appreciated. I'm at my wits end trying to fix this. I'm really trying not to bring this to the dealer but although drivable under 4000 rpm, I'd really like to have the throttle issues resolved. Thanks again Mark
  2. Hey everyone Been having some throttle cut out issues and I've been told by 2 different shops that my DME needs to be replaced. I've tried serching for DME threads and just wanted to make sure I can swap a DME set that I found on ebay. 2000 Porsche Boxster 986 Engine Computer Security Immobilizer Set Key 2 7 51 067 | eBay The only difference is my box is a tiptronic and this is from a 5 speed. My box is a 2000 and this set is also from a 2000. Am I ok to do a straight swap without any extra programming? I just don't want to do the swap and try to start the car if it could cause more damage. Thanks for your input/advice.
  3. Sorry for resurrecting an old thread but my 2000 boxster is also having this problem. Did any of you solve this problem? Thanks!
