The seascape dvvt engine has no power, high fuel consumption and the fault light is on.

Hello, dear! This involves many problems. Make a simple judgment by yourself according to the steps: 1, see if there is exhaust (under heavy load and no load) 2, the climbing speed under heavy load can't be reduced 3, (see whether the oil pressure gauge is accurate) 4. After all above are normal, replace the oil pump. I hope my answer can help you, please set it as the best answer! thank you
