I thought I had an egr problem but I forgot I deleted it years ago....When the car gets warm it will die when accelerating. You let off the gas and it will smooth out and run fine. When it happens the tach will drop like there is no voltage getting to it. Could this be a DIS issue, a coil pack or even a crank sensor going bad???I replaced the crank sensor last year... it completely died when that went out..It's not throwing any codes so I'm at a loss as to what it could be...The fuel pressure is in range so I'm thinking it has to be something electrical
