Thanks for allowing me to join the group. My Ranger starts and idles great. However after about 2-3 minutes of driving the engine bogs down and the more I push the accelerator the worse it gets. I did a compression test which was well into the green all 4 cylinders, replaced the spark plugs, both coil packs, engine coolant temp sensor, throttle position sensor, egr sensor, maf sensor. No help. I tested the fuel pressure which reads 40-45 psi,and when I pull the vacuum hose from the fuel pressure regulator pressure rises to about 50 psi. I rigged the pressure gauge so I could read while driving. When the engine runs well pressure is 40-45. When the engine bogs down when accelerating pressure drops to 10-15 psi. The more I push the accelerator the lower the pressure goes but never enough to stall the engine. Two questions: Is The pressure drop abnormal? And if so any suggestions as to the cause? Thx in advance for any suggestions .
