I have been noticing that on some fuel injected vehicles the voltage drops to battery voltage 12.x-12.6 volts during wot operation. Does the pcm stop fielding the regulator during wot? Maybe you know something I don't?
During Clear Flood operation injectors are turned off when a high a TP signal is detected by the pcm in ignition on engine off state. My question is how long are the injectors turned off for? or are they off until a threshold of xxx engine RPM is reached?
I don't feel like taking the rail off...
On another forum I regularly visit I came across an interesting thread, when replacing the catalyst for a less restrictive hollow test pipe will increase or reduce mpg?. So which one is it, I am curious to hear your answers. Thanks
