Well second one in less than a week,was called to one of my customers today for a code E-38,truck would start and run good and has throttle response for a couple minutes then nothing,regualtor is fine PSI is good at 4.5-5 PSI,getting another injector in the AM and going to this customer and install,is on a diffrent model Nissan(MU1F2A25LV) but same engine.
When it starts loosing throttle resonse if you shut the truck off it will start right back up and have response again for a couple minutes then looses it again.
