my car just died/stalled out 3 times when i installed the VAFC(died when first starting the car, idled for less then a minute then RPM'S got lower and just stalled out). put vtecnology's setting and Brandon B's setting which were somewhere around the beginning of the post(VAFC library thread)...did i forget to set something? i changed all the settings in the setting part of the menu and did the etc. menu settings according to RT's in another post.i didnt touch display setting, are you supposed to?? please help , i just unplugged the harness and plugged back in the regular wires to the ECU and my car is fine. one more thing the check CEL came on(blinked once the second time i did it),is that supposed to happen?(it turned off when i took the harness and vafc off). am i supposed to reset the ECU?(unplug a fuse for 30 seconds???)

please help ASAP...thanks,i really appreciate all the help i can get.

double check the brown wire and how it is wired with the manual. that wire can cause many problems if not wired correctlly

Check the cable connection.
It sound like the connection between the harness and the VAFC is not connected properly. This can gives you the CEL and stalling

got that from another post...maybe the harness was wired wrong, their can only be one or two wires mixed u if any ause all the other's are labeled...

Mike i'll call u up one of these days this week to see if you can help me out...hopefully your not busy.

thanks for theories guys

did you check your initial settings? When I reseted mine, I forgot to change the cylinder type and it kept staling on me. It wouuldn't even start. Make sure you have the right initial settings
