Does no poop mean it doesn't belch black smoke or that it doesn't have any pickup?I changed the EGR Valve and the EGR Solenoid and the car is in limp mode. Restarted numerous times and will not reset. Pulled and plugged vac line to EGR Valve and am out of limp but in diminished performance. No poop on hills. EGR system is clean. Help!
