The injectors are new but that doesn't mean that they are working proply, i took out the cold start valve left it hooked up, and filled the hole with another one. Ran car but no fuel came out of the c.a.v. I have new fuel pump, new temp sensor, on the bottom of the throttle body there is a boost controlled deceleration valve but nothing electrical or air is hooked up as i can`t find any info on this device, or if i even need it. the dyno guy said not to use vac advance setup. Cheers
