Don't feel too bad...the greater majority of us,( I include myself in this statement) started off "VX life" in your shoes...having little experince with "modern" vehicle technology.
The last cars I did any "serious" work on before the VX, were a 64 Impala, & a 70 Mustang...gave me a grasp of the basics, but little else that would be helpful in understanding the workings of a modern EFI system with computer controlled "everything".
Just keep hangin' around, & reading the forums...it's amazing how much information you can find around here...
Also, THANKS, to all those that have contributed to my continuing education on this, my favorite subject ever...![]()
