The MAF plug is and has been in place the whole time. No doubt about that. And I'm quite sure there are no vacuum leaks but I will tighten everthing again and see what I get. I also checked the calibration... It's calibrated to the 2000 CSVT (theres a start), and for the 19 injectors, and a concial filter. All correct, unless Ford changed the injectors for 2000. What do you guys think?
